Let’s stop pretending all weeknight dinners need to be sad and fast. This one? It’s both fast and makes you feel like you just ordered the special at a little hidden French bistro.
Tender, fall-apart beef (yes, even on a weeknight), silky mushrooms, and a creamy-tangy sauce that basically spoon-feeds you comfort. No weird ingredients, no complicated steps. Just you, your skillet, and a dish that makes Tuesday feel like a weekend treat.
If you really want that melt-in-your-mouth feel without buying filet, go for sirloin tips or flat iron steak — just don’t overcook them. Searing them quickly and simmering gently in broth gives them that rich, slow-cooked vibe without the wait.
Ingredients
1 lb beef tenderloin tips or sirloin, cut into bite-sized pieces
Season + Sear the Beef Pat beef dry and season generously with salt and pepper. Heat oil in a large skillet over medium-high. Sear beef in a single layer for 1–2 minutes per side until browned but not cooked through. Transfer to a plate.
Build the Flavor Base In the same skillet, add butter and onions. Sauté 2 minutes, then add mushrooms. Cook until soft and golden, 5–6 minutes. Stir in garlic, paprika, mustard, and Worcestershire.
Make It Saucy Pour in the broth. Scrape up the browned bits (they’re gold). Simmer for 3–4 minutes to reduce slightly. Optional: Stir in cornstarch slurry if you want a thicker sauce.
Bring It All Together Lower heat. Return beef to skillet. Simmer 3–5 minutes, just until beef is tender and cooked through. Remove from heat and stir in sour cream until smooth and dreamy.
Serve with Joy Spoon over buttered egg noodles, mashed potatoes, or even cauliflower mash. Garnish with parsley. Stare lovingly at your plate before devouring.
