Pressure Cooker Beef Carbonnade (Belgian Beef Stew)

Kenji Alt’s Pressure Cooker Caramelized Onions is a brilliant idea. He uses the sealed environment and high heat of a pressure cooker to caramelize onions without the risk of burning. Normally, caramelized onions are finicky – you have to stir constantly for 20 to 30 minutes. In the pressure cooker, it takes the same amount of time, but it’s hands-off; no stirring, just show up when the onions are done. 3

The moment I saw these onions, I thought about beef carbonnade – Belgian beef, beer, and caramelized onion stew. It was perfect – a first stage under pressure to caramelize the onions, then a second stage under pressure to cook the stew. Easy, right?

Um…the fates laughed at me when I said that.4 This recipe took a bunch of tries for me to get right. Now, all were pretty good – I had a lot of leftover beef stew for lunch, and enjoyed it – but I did learn a few things along the way:

  • 2 pounds of onions needs a little extra water in my pressure cooker to build pressure before it overheats and the onions start to burn…but 3 pounds of onions release so much liquid that they don’t brown properly, and need an extra 20 minutes of simmering. In an Instant Pot, stick close to 2 pounds of onions, and add 1/4 cup of water to help get things started
  • Stirring flour into the stew is great for thickening, and traditional for the recipe – but can also overheat the cooker if it thickens the liquid up too quickly. (Like, if you try to add it to the pressure caramelizing onions.) I add a bottle of beer and a cup of chicken stock to the pot for the stew stage, to keep everything loose enough to come up to pressure.
  • This recipe traditionally has thin strips of beef; flat iron steak is the perfect cut for this. (To save money, substitute chuck roast – but it will require more knife work to get it into the required shape.)
  • Browning the beef. I tried this recipe without browning, with browning the whole flat iron steak and then slicing, and slicing first then browning the slices. They were all good, but the more browning, the better the flavor. I know browning batches of beef is annoying, and takes time, but it is worth it to build the flavor.

If you’re looking for a “ dump everything in the pot and pressure cook” weeknight meal, this is not the recipe for you. But, if you want to show off, this is a fantastic beef stew, made quicker and easier by the pressure cooker.

Pressure Cooker Beef Carbonnade recipe – use the pressure cooker to caramelize the onions, and take most of the work out of this classic recipe.



Browning the beef

  • 1 tablespoon butter
  • 2 pounds Flat Iron steak (or chuck blade steak, or chuck roast), cut into 3 inch long by 1/2 inch thick strips
  • 2 teaspoons Diamond Crystal kosher salt or 1 1/2 teaspoons fine sea salt

Caramelized Onions

  • 2 tablespoons butter (for the onions)
  • 2 pounds of onions, peeled and sliced thin
  • 1/2 teaspoon baking soda
  • 1 teaspoon Diamond Crystal kosher salt or 2/3 teaspoon fine sea salt
  • 1/4 cup water

Stew Ingredients

  • 1/4 cup flour
  • 12 ounces Belgian dark brown ale (like Ommegang Abbey Ale or Chimay)
  • 1 cup chicken stock or water
  • 1/2 pound of carrots, peeled and cut into 3 inch lengths
  • 2 sprigs fresh thyme (or 1 teaspoon dried thyme)
  • Minced parsley for garnish


  1. Brown the beef: Melt a tablespoon of butter in the pressure cooker pot over medium heat (sauté mode in an electric PC). Sprinkle the beef with 2 teaspoons of salt, and then brown in 2 to 3 batches, about 6 minutes per batch, flipping halfway. Move the beef to a bowl after it is browned.
  2. Pressure cook the onions: Melt 2 tablespoons of butter in the pot. Stir in the onions, baking soda, and salt. Stir for a minute or two, scraping the bottom of the pot with a wooden spoon until all the browned bits of beef are loose and the onions are coated with salt and baking soda. Add the water, lock the lid and pressure cook on high pressure for 20 minutes in an electric PC, or 16 minutes in a stovetop PC. Quick release the pressure and remove the lid (carefully – the steam is hot). Set the heat to medium (or an electric PC to sauté mode), and cook, stirring often, until the liquid reduces and the onions are dark brown and caramelized, about 5 minutes.
  3. Pressure Cook the stew: Stir the flour into the onions and cook for 1 minute, stirring often. Stir in the beer and bring to a simmer, scraping the bottom of the pot to loosen any browned bits of onion or flour. Simmer the beer for 2 minutes to cook off some of the alcohol. Stir in the chicken stock, browned beef (plus any juices in the bowl), carrots, and fresh thyme sprigs. Lock the lid and pressure cook on high for 12 minutes in an electric PC, or 10 minutes in a stovetop PC. Quick release the pressure and remove the lid (again, be careful – the steam is hot).
  4. Season and serve: Discard the thyme sprigs, and then taste the stew. It will probably need a little salt (especially if you used homemade chicken stock) and a lot of pepper. Serve, sprinkling with minced parsley as a garnish.

  • Pressure cooker plus frypan for browning: speeds up the browning, make sure to use
  • It’s traditional to serve this stew with buttered noodles, but I love the caramelized onion sauce with mashed potatoes.

Hi! I’m Mike Vrobel. I’m a dad and an enthusiastic home cook; an indie cookbook author and food blogger with a day job, a patient spouse, and three kids who would rather have hamburgers for dinner.


  1. Steven Grossmann says

    Hi Mike,

    I am concerned about the 10 minutes to cook chuck, should it be longer?

  2. Claire says

    Hi! Thanks for the recipe! May I ask why you pressure cook the onions? Wouldn’t just sautéing them for 10 minutes or so achieve the same results a lot quicker? Thanks!

    • You have to sauté onions for 20 to 30 minutes to get them properly caramelized – the pressure cooker makes it a much easier, hands off recipe. Now, if you’re OK with onions that are just starting to brown, you can sauté the onions for 10 minutes, and continue from there.

  3. Helen Adams says

    I had the same problem with less than 2 lbs of onions (too much liquid) but since I was making French onion soup it was okay.

    Maybe when I do it again (to make your lovely recipe) I will strain before browning and save liquid?

  4. Denise Howarth says

    I have never reviewed a recipe before but I had to comment on this outstanding dish. I followed the recipe pretty much exactly, used my beloved Instantpot and it was nothing short of amazing. I used a Chuck roast and I did have to cook it longer (the stew setting seems about right) Served it with mashed potatoes as suggested… Will definitely be making this again!

  5. Mike T says

    Great recipe, this made me popular amongst the family on the first try. 🙂 I used sweet onions, and it tasted great, but I think they were juicy enough to release some extra water when pressure cooking. You mentioned extra simmering time when you had 3 lbs of onions… Do you let it go until most of the liquid is gone? How soupy should it be at that point?

    • I let it go until the onions are caramelized and brown – the liquid never goes away entirely. (Or, at least, it would take a long time simmering for that to happen.)

  6. Casey says

    Hi there. Tried this yesterday. The pot appeared to come to pressure and counted down as expected. When I went to QR the pressure, no steam escaped. Does this have something to do with the flour already in the stew, or do you suspect my instantPot was having technical difficulties? The flavours were nice but my beef was much chewier than I would have liked after such a short cook time. Thanks!

    • That sounds like instant pot problems, if it counts down correctly. (You would get an overheat warning if the flour was causing problems – the pot would never come up to pressure, and the countdown wouldn’t start.). To check, run your pot with nothing but 2 cups of water in it and see if it pressurizes properly.

      • Casey says

        Thanks. I worried it might be an issue with the float valve and/or that I wasn’t getting a proper seal because there was hidden gunk spatter along the sealing ring from the onion phase. At any rate I’ll give it a whirl again with something simpler. Cheers.

        • Casey says

          PS – I’m curious – What’s the rationale for adding the flour at the stage you do, rather than after the pressure cook phase on saute mode as is done in other recipes?

          • I think it helps the flavor to cook the flour in with the rest of the ingredients.

  7. Kate MacKay says

    I make a version of this all the time (my sister lives in Belgium, so I’m well acquainted with their fabulous cuisine). Here’s something I found that kicks it up a notch… I either substitute the Belgian ale with a chocolate stout … Can’t remember the brand name right now, or if I’m out of that, I add 1/8 of a square of baking chocolate. I think the squares are measure at 1 oz so 1/8 of that… Just a touch but oh-la-la. It doesn’t really change the taste overall but it seems to smooth everything out.

  8. Love this recipe. Would you substitute additional chicken broth for the ale for a nonalcoholic choice?
