Ingredients
Beef and Seasoning
- 1.5 lb beef sirloin or flank steak, sliced thinly against the grain into 1/2-inch strips
- 1 tsp kosher salt, plus more to taste
- 1/2 tsp black pepper
- 1 tsp paprika (sweet or smoked)
- 1 tbsp all-purpose flour (for light dusting)
Base and Sauce
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1 medium yellow onion, thinly sliced
- 10 oz cremini or white mushrooms, sliced
- 2–3 garlic cloves, minced
- 1 tbsp tomato paste
- 1 tsp Dijon mustard
- 1 cup beer (lager or pilsner; see Beer Notes)
- 1/2 cup low-sodium beef broth
- 1 tsp Worcestershire sauce
- 1/2 cup sour cream (full-fat for best texture)
- 1–2 tsp lemon juice or red wine vinegar (to finish, optional)
- Chopped fresh parsley, for garnish
To Serve
- Cooked egg noodles, mashed potatoes, or buttered rice

Why Beer Works
- Beer brings malty sweetness, gentle bitterness, and toasted grain notes that deepen the gravy without making it heavy.
- Lager or pilsner reduces cleanly, enhancing the seared beef and mushrooms while keeping the sauce bright.
- The carbonation and alcohol lift browned bits from the pan, building flavor fast.
Instructions
- Prep the beef
- Pat beef dry. Toss with salt, pepper, paprika, and a light dusting of flour. The flour helps browning and lightly thickens the sauce.
- Sear the beef
- Heat a large skillet or sauté pan over medium-high. Add 1 tbsp butter and the olive oil.
- Sear beef in 2 batches, 1–2 minutes per side, just until browned (do not fully cook). Transfer to a plate. Add a touch more oil if the pan looks dry.
- Sauté vegetables
- Reduce heat to medium. Add remaining 1 tbsp butter.
- Add onions with a pinch of salt; cook 3–4 minutes until softened.
- Add mushrooms; cook 5–6 minutes, stirring occasionally, until browned and their liquid evaporates.
- Stir in garlic and cook 30 seconds until fragrant.
- Build the pan sauce
- Clear a small space in the pan; add tomato paste and cook 1 minute to caramelize.
- Stir in Dijon and Worcestershire.
- Pour in beer, scraping up browned bits. Add beef broth and bring to a lively simmer. Simmer 5–7 minutes to reduce by about one-third.
- Return beef to the pan
- Add any beef juices back to the skillet and simmer 2–3 minutes more, just until the beef is cooked through and tender. Keep the simmer gentle to avoid toughness.
- Finish creamy
- Reduce heat to low. Stir in sour cream until the sauce turns silky and light brown. Do not boil after adding sour cream.
- Taste and adjust with salt and pepper. If you want extra brightness, add 1–2 tsp lemon juice or vinegar.
- Serve
- Spoon over buttered egg noodles, mashed potatoes, or rice. Garnish with chopped parsley.
Tips for Tender Beef and a Silky Sauce
- Slice against the grain: Thinner, cross-grain slices stay tender even with quick cooking.
- Quick sear only: Browning adds flavor; overcooking in this step makes beef tough. Finish cooking gently in the sauce.
- Reduce, then enrich: Let beer and broth reduce before adding sour cream. This concentrates flavor and keeps the sauce from thinning out.
- Keep it gentle: After sour cream goes in, keep heat low to prevent curdling.
- Balance the beer: If the sauce tastes slightly bitter after reducing, a small pinch of sugar or an extra spoon of sour cream smooths it out. A squeeze of lemon also brightens.
- Control thickness: If too thick, splash in a bit more broth. If too thin, simmer a minute longer before adding sour cream.
Variations
- Steakhouse twist: Add 1 tsp cracked pepper and finish with a pat of butter for gloss.
- Herby: Stir in 1 tsp fresh thyme or 1 tbsp chopped dill at the end.
- Earthier mushrooms: Swap in part shiitake or porcini (rehydrated) for deeper flavor.
Beer Notes
- Best choices: Clean lager or pilsner for balanced malt and gentle bitterness. A light amber works if you want mild caramel notes.
- Avoid: Very bitter IPAs (can taste harsh when reduced) and dark stouts/porters (too roasty for classic stroganoff).
- Nonalcoholic option: Use a good NA lager; you’ll get malt aroma and balance without alcohol. Adjust salt and acidity to taste.
