The best French Onion Soup that has ever crossed your lips! Comes together in less than 30 minutes, not even kidding right now! This Instant Pot version is so simple and it's gonna blow you away with how rich and flavorful it is!
Do you love French Onion Soup like I love French Onion Soup?
Do you hate caramelizing onions for 30 minutes like I hate this pungent task? I'll take folding laundry and cleaning up kids' dried toothpaste off the bathroom counter any day.
Speaking of which, why has no one invented a failproof system for keeping toothpaste under control?!
The last 2 times I remember making onion soup was when I lived in my brother's basement (the smell went up through the vents and his family smelled like onions for 2 weeks, oops) and again at my mom's (she opened up all her windows and doors and said she didn't care how good it tasted, I was not allowed to make it there ever again).
Funny, I don't think I've ever made it in my own home . . .
Poor stinky, delicious onions. Banished time and time again.
Well you guys, I cracked the code!!! Oh, happy happy day when I figured this trick out!!!
The Instant Pot is taking one for the team here and caramelizing those onions in less than 10 minutes with only about 2 minutes of your helping hand required.
WHY YOU WILL LOVE THIS EASY, CLASSIC FRENCH ONION SOUP
- Never again will you need to stir, stir, stir your onions into sweet, soft submission. A little butter, seasoning, a sprinkle of baking soda (the secret quick caramelizing ingredient) and some pressure cooking action get those onions brown and tender in no time
- If you want to read more on how baking soda creates a higher pH environment to increase browning, head to the smarty pants over at Cook's Illustrated for an interesting article on Quicker Caramelized Onions.
- Take it outside! Very often I take foods like Pot Roast and soups outside to cook in the Instant Pot. This means I can eat onion soup without smelling like a boys locker room for a week. Another point for electric pressure cooking!
- Crunchy croutons covered in cheese, what's not to love there.
HOW TO MAKE THE BEST FRENCH ONION SOUP IN THE INSTANT POT
- Melt butter in the pressure cooker until just barely starting to brown
- Stir in sliced onions and seasonings, let cook just until the onions start to release liquid, about 3 minutes
- Pressure cook on high for 6 minutes, do a quick release of the pressure (smells amazing, but I suggest doing this outside if possible)
- Add broth, tomato paste, and a couple drops of hot sauce (if you like heat), use saute to heat it through
- Ladle into an oven-safe bowl
- Add homemade croutons and shredded cheese on top and place under the oven broiler until the cheese is melted and the croutons are extra brown and crunchy
SEE RECIPE CARD BELOW FOR DETAILED COOKING INSTRUCTIONS
You are going to have people pounding down your door for this recipe, I guarantee it.
If you cook it outside like I do, you're going to have animals and curious neighbors on your porch searching for the source of that glorious smell.
It's healthy, easy, quick Instant Pot French Onion Soup! That is a combo of words you will be very hard pressed to find together ever again.
There were two soups this month that really made me work hard to make them truly special in a sea of so many versions: Zuppa Toscana and this French Onion Soup.
But with lots of perseverance and tears (from slicing onions anyway – I'm not quite weird enough to cry over soup), I figured this one out and I seriously cannot wait for you guys to try this.
Enjoy!
VARIATIONS
- To make this a Vegetarian French Onion Soup, omit the Worcestershire sauce and swap the beef broth for vegetable broth
- If you want something a bit more hearty, this flavorful broth is a perfect canvas for adding other ingredients too. Shredded chicken, steak, ravioli, gnocchi, steamed veggies, beans, etc.
EXTRA TIDBITS
HOW TO CUT ONIONS WITHOUT TEARS
See the recipe card for details on how to properly slice onions into perfect moon shapes, but here are some tricks that actually work to avoid the dreaded tear fest that accompanies slicing a pile of onions.
- Steal your kid's swimming goggles. There's a little bit of swallowing your pride on this one (oh the teasing I get), but it works. You can also buy onion goggles if you wanna go there
- A fan! This works amazingly well. Just a small tabletop fan to blow away the sulfur fumes and you can slice away without the need to reapply makeup when you're done
- Chill it. Place peeled onions in the freezer for 10 minutes. This actually works, however, I could be done slicing onions by the time I pull them out of the freezer, soooooo there's that
- Rachael Ray's advice, “Just put your big girl pants on already and get the job done!” This tends to be my go to method, besides, it's good entertainment for the kids to watch
BEST CHEESE FOR FRENCH ONION SOUP
My answer will not be supported by Google here, but I LOVE Asiago on french onion soup. It has a strong flavor that compliments the broth beautifully, and since it's so flavorful, you don't need to use an enormous amount.
If you're looking for the classic cheese topping, go with Gruyere. Other options are white cheddar, fontina, or swiss.
BEST BREAD FOR THE BEST FRENCH ONION SOUP
Okay, sorry, this is a Google rule breaker too. Go for a hearty bread like a baguette, sourdough, artisan bread or this amazing Instant Pot Whole Grain Crusty Bread or Rosemary Asiago Crusty Bread.
Cut it up into large bite-size pieces and make your own homemade croutons by coating it with olive oil or melted butter, salt, and pepper. Cook in a 400° oven until browned and crunchy, about 10 minutes. Watch closely so it doesn't burn!
Traditionally french onion soup uses a baguette slice or two for the topping so when you try to take a scoop of soup, you have to wrestle with a soggy, tough baguette to get a single bite of bread with a spoonful of soup. Soggy bread, messy mess, stressful eating – be gone.
I implore you to try the homemade croutons! You'll get crunchy bites of bread in each mouthful and have enough of them to last you through the entire bowl of soup.
HOW TO MAKE HEALTHY FRENCH ONION SOUP
While being a broth-based soup, french onion soup isn't typically the healthiest soup on the menu, but I argue that it should be, so here's how I altered it.
- Most french onion soups start out with a LOT of butter for flavor and for carmelizing the onions. Using the pressure cooker, I reduced the butter to just a few tablespoons. For rich full flavor, I use spices, Worcestershire sauce, and tomato paste
- Use flavorful cheese! As discussed above, use a stronger tasting cheese and you can use less of it without sacrificing on flavor. Asiago all the way!
- For the croutons, try to hunt down a whole grain option. That's tough to come by in grocery stores, but not impossible, especially in specialty bread shops. Or of course, make your own.

Recipe adapted from a Top Secret Recipes version of Panera Bread French Onion Soup
Welcome! I’m Marci, wife to my motorcycle dream man and mother of 3. I have a passion for creating and cooking delicious masterpieces in my kitchen and am ecstatic to share my discoveries on TIDBITS! I like my food tasty, wholesome, memorable, and always, ALWAYS followed by dark, salty chocolate.
I’ve made this twice, and its just about the most delicious thing ever. Tonight I was in a hurry and wasn’t thinking amd just typed in “French onion soup” recipe and grabbed the top recipe that popped up. It just was soooo bland, I had to find yours and add all the stuff they missed. And I still don’t think its quite right. I won’t make that mistake again,your recipe is perfect in every way. As for cheese, I use Swiss, its soooooo good! Though one of these days ill try your suggestions, I just usually dont have them on hand.
★★★★★
Marie, I’m so glad you love it! I have no patience for bland French onion soup either, haha! It has to be rich and flavorful every time. I love swiss as well, but asiago is sharp and surprising. I love it.
Made this the other night. So easy and amazing. It’s on my make again list
Starla, I’m so glad you liked it 🙂
Marci, my dear sweet love, I am siding with you on this issue of how much cheese belongs on French onion soup. I lalalalove cheese, don’t misunderstand my passion for cheeses ranging from hard cheeses like Romano to soft, creamy Camemberts but this soup is much to rich and delicious to create a conflict between competing flavors. I made this Thursday evening after reading your blog, I will admit I was a bit skeptical since I have spent the four to five hours making French onion soup the traditional way, and this soup recipe’s flavour is spot on and soooooooo much easier to make. So my dear, despite any criticism from other cheese aficionados, I will stand firm with you.
Tamara, Oh I just got chills! I’m so excited that you loved it and that we can concur that it’s just too darn good to cover up with way too much cheese. I’m making it again this week, it just makes me so happy to eat it. I wish I could join you at your table for a big bowl!
by all means, never ever commit that faux pas again by saying that there might be too much cheese on French onion soup–that can never happen. As a Wisconsin native, cheese was one of our first foods–i think my mother melted it into my bottle, and likely the reason for the extensive cellulite on my legs!
Karen, hahaha!!! That comment was too good! Have you tried this one yet? I think you would adore it.
I made this tonight and it was wonderful. Have to say that it was so filling. I followed the recipe to a T and would not change a thing. Will be making this again.
★★★★★
Margie, isn’t it great!? It just feels so good to eat this one, right!?
Yummy! Just made made this and it has great flavor. I read an above comment about the onions being too overcooked. I did make large cuts and decided to cook for 7 mins. I think they are a little over done still. I honestly think 5 or 6 would be perfect. I plan on trying again because yhe flavor and simplicity are perfect for me! Thanks!
★★★★
Got a burn notice after two minutes of pressure cooking. Onions definitely lacked liquid. Next time, I’ll add liquid beforehand if I think the onions are too ‘dry’. Will finish the soup on the stove.
★★★
Ina, dang, I’m sorry to hear it didn’t work for you! I love this recipe! What pressure cooker do you have? I’m curious because I’ve heard a lot of people say that the newer IP models display the burn notice more easily.
I did as the recipe told me… after cooking it looks like most of my onions disintegrated… I add added 2 more onions and put it on 2 minutes to recook… did I slice the onion to thin initially??? Why the tomato paste???
★★★★★
Pam, The onions may have been sliced to thin, my onions are soft but not disintegrated when I make it. I’m curious, what size of pot did you make it in? I’m noticing my 8 quart over cooks some recipes so I’m wondering if that could be at play here. The tomato paste I add for more layers of flavor. I love the addition of the paste!
Hi… My IP is a 6 quart… reviewing the photos today I do think I must have sliced onions to thin… we liked the tomato paste mixed in as well… nice flavor for sure… will make again😋😋😋😋😋
★★★★★
Concerning the French onion soup I have a question about cooking the onions in the IP.
If I put the onions and other ingredients in the butter and then cook 3 min. , you said put the lid on IP AND COOK FOR 8 min.
Where’s the liquid for the pressure cooker?
I’m getting ready to fix the soup and seems to me that the onions might burn.
Are the directions correct?
Thanks so much🦋
Sandra, Trust me on this one! The onions create a ton of liquid when they heat up, plenty enough to create the pressure needed. I’ve done it several times now without issues, I feel like I need to knock on wood saying that though!
Another soup success! We used to eat this soup as kids but I never bothered to try cooking it, as if seemed like too much work. This was simple and yummy.
I cut onions holding the corner of a paper towel with my mouth…it seems to keep most fumes away. I cooked it on the stove so I could keep the fan above it on high….and covered the quick release with a folded towel… so I think house smell was minimized?
Sourdough made for excellent croutons. Got oven safe bowls… from the dollar store (lol). Splurged on asagio … a great choice.
I am determined to try all this months soup..so far it’s a 3 for 3 win! Thanks again Marci. 😊
★★★★★
Shelley, Those are great ideas for reducing the smell, I’ve never thought of the paper towel trick but you better believe I’m gonna try that tomorrow! I’m so psyched that you’re trying all the soups, how fun!
Hello to all,
Onion Soup in the IP is a winner. Perfect recipe that I must admit I tweak a bit with the addition of a good shot of Dry Sherry when adding the broth. The warming process dissipates any alcohol so no worries there.
However, if I may toss in my 2-cents worth regarding onions. It has been a great many years since an onion has made me cry and what I’m going to say will no doubt be met with gasps of horror OMG! NoNoNo!!!!! My Mother did it so I grew up not knowing any better. I have always kept my onions in the crisper in the fridge along with other items that I might have on hand such as carrots, turnips, cabbage, beets, whatever. All items are in separate un-sealed bags and I have never encountered a problem with the transfer of odours/flavours nor does it affect the quality of the onions. It truly works, No More Tears.
★★★★★
Laura, haha, that made me laugh. My mom always put onions in the fridge and I only stopped doing it when I got older and started watching food network. Mom is always right? Maybe so!
