How to Make Instant Pot Mushroom Stroganoff

For the Base:

Sauté Aromatics: Melt butter in the Instant Pot on sauté mode, then cook chopped onion and garlic until golden and fragrant, about 3 minutes.
Add Mushrooms: Stir in sliced cremini mushrooms, cooking until they release moisture and turn golden at the edges, about 4–5 minutes.
Deglaze Pot: Pour in vegetable broth, Dijon mustard, and paprika, scraping any browned bits off the bottom for a rich, deep flavor.
Pressure Cook: Seal the lid, set to high pressure for 5 minutes, then perform a quick release to preserve mushroom texture and avoid overcooking.

For the Creamy Finish:

Blend Sour Cream: In a small bowl, whisk sour cream with flour until smooth, then stir into the hot stroganoff base until the sauce turns silky and slightly thickened.
Combine and Simmer: Switch to sauté, gently stir the noodles into the creamy sauce, and cook for 2 minutes until the sauce clings to each strand.
