French Onion Beef Stroganoff is ready in a little over an hour by making use of your Instant Pot, and is full of caramelized onions, mushrooms, and the most flavorful, deep sauce.

French Onion Beef Stroganoff

This Instant Pot version of French Onion Beef Stroganoff takes the comforting flavors of caramelized onions and tender beef, then pulls in classic stroganoff elements like mushrooms and sour cream for a one-pot dinner with major flavor. Using chuck roast keeps things hearty and satisfying, while pressure cooking speeds everything up without sacrificing taste.

Cooking the onions low and slow in butter builds a sweet-savory foundation, while the mushrooms deepen the flavor. Wine and beef stock create a rich braising liquid that reduces into a gravy-like sauce. The sour cream ties it all together and gives that signature stroganoff finish.

You can make tweaks based on what you have: skip the wine, change the cut of beef, leave out the mushrooms, or serve it over mashed potatoes instead of noodles. It’s forgiving, but still gives you that wow factor with very little effort.

I LOVE fresh Chanterelles, and this is the perfect match for them. By the end of the cooking period they are so full of beefy, delicious flavor. YUM. I am having them again for lunch today, in fact.

If you have access to Chanterelles where you are, you’ll definitely want to pick up a bunch. Make this french onion beef stroganoff, and also my Cream of Chanterelle soup. You will not regret it.

If Chanterelles aren’t in season, crimini or button mushrooms also work really well.

I use a sturdy “homestyle” egg noodle for this dish, but you can use any kind you’d like. Traditional egg noodles are also good, as would be a big pile of garlic mashed potatoes.

Want to make your own egg noodles? I have a fantastic recipe here. My Great Grandma’s Homemade Soup Noodles has been tested and retested and never fail. Fair warning though – I made those my first year of blogging and haven’t re-shot the photos yet, so if you found my blog later in its life you can see just where I started from.

How To Make French Onion Beef Stroganoff

This is just the overview so you can see what you’re actually getting into here. When you are cooking, you’ll want to use the full recipe at the bottom of the page.

1. Caramelize the Onions
   Set your Instant Pot to Sauté and melt the butter. Add the diced sweet onions, baking soda, salt, and pepper. Stir regularly and cook for about 10–15 minutes, or until the onions are soft and starting to brown. The baking soda helps speed up caramelization without needing a full hour on the stovetop. This step lays the flavor foundation, so take your time here and let the onions really develop color.

2. Build the Flavor Base
   Stir in the sliced mushrooms and cook them down for a few minutes until they release their moisture and start to brown. Once the mushrooms have cooked, season your roast with garlic salt and seasoning salt, then place it directly on top of the onion-mushroom mixture. Add the red wine and the water mixed with au jus seasoning (or beef broth if you’re skipping the mix). Scrape up any browned bits from the bottom of the pot. Those bits are packed with flavor and will enrich your sauce.

3. Pressure Cook the Roast
   Seal the lid and set the Instant Pot to Meat/Stew mode or Manual/High Pressure for 55 minutes. Let the pressure release naturally for about 15–20 minutes. This gives the roast time to finish cooking gently and helps lock in moisture. Once the pressure has released, carefully open the lid and remove the roast. Set it aside on a large plate or cutting board to cool slightly before shredding.
4. Strain and Thicken the Sauce
   Remove the onions and mushrooms if you want a smoother sauce (optional). If there’s excess fat on top, skim it off with a spoon. Set the Instant Pot back to Sauté and bring the cooking liquid to a simmer. In a small bowl, whisk together cornstarch and water to make a slurry, then slowly whisk it into the sauce. Keep stirring until the sauce thickens to your liking. If it gets too thick, thin it with a bit of water or broth.
5. Finish and Serve
   Shred the beef using two forks and discard any large bits of fat or connective tissue. Stir the shredded beef back into the thickened sauce. Just before serving, stir in the sour cream for a creamy, tangy finish. Serve hot over buttered egg noodles, mashed potatoes, or rice. Garnish with fresh parsley if you want a little color on top.
