Every time I make something with mushrooms now, I think of Emily’s table—the way ten dishes from ten different homes somehow became one meal that felt entirely whole. The cream of mushroom in Mom’s green bean casserole has always been the flavor I reach for when I need to feel grounded, and this Mushroom Pepper Steak captures that same deep, savory comfort in a way that’s become a weeknight staple in our San Diego kitchen. It’s the kind of dish that would hold its own at any potluck table, and one I think Ryan would say a quiet grace over—because the hands that make it matter just as much as what ends up on the plate.
Mushroom Pepper Steak
Prep Time: 15 min | Cook Time: 25 min | Total Time: 40 min | Servings: 4
Ingredients
- 1 1/2 lbs flank steak or sirloin, thinly sliced against the grain
- 2 cups cremini or baby bella mushrooms, sliced
- 1 green bell pepper, sliced into strips
- 1 red bell pepper, sliced into strips
- 1 medium yellow onion, sliced
- 3 cloves garlic, minced
- 2 tablespoons soy sauce
- 1 tablespoon Worcestershire sauce
- 1 teaspoon freshly ground black pepper
- 1/2 teaspoon smoked paprika
- 2 tablespoons olive oil, divided
- 1 tablespoon cornstarch
- 1/2 cup low-sodium beef broth
- Salt to taste
- Fresh parsley, chopped, for garnish
Instructions
- Marinate the steak. In a bowl, combine sliced steak with soy sauce, Worcestershire sauce, black pepper, paprika, and cornstarch. Toss well to coat and let sit for at least 10 minutes while you prep the vegetables.
- Sear the beef. Heat 1 tablespoon olive oil in a large skillet or wok over high heat until shimmering. Add the steak in a single layer and sear without stirring for 1–2 minutes, then stir-fry for another 1–2 minutes until just cooked through. Transfer to a plate and set aside.
- Saute the vegetables. Add the remaining tablespoon of olive oil to the same skillet over medium-high heat. Add onion and both bell peppers and cook, stirring occasionally, for 4–5 minutes until softened and beginning to char at the edges.
- Add mushrooms and garlic. Stir in the mushrooms and garlic and cook for another 3–4 minutes until the mushrooms have released their liquid and turned golden brown.
- Build the sauce. Pour the beef broth into the skillet, scraping up any browned bits from the bottom. Return the steak and any resting juices to the pan. Stir everything together and cook for 2–3 minutes until the sauce thickens and coats the beef and vegetables.
- Taste and serve. Adjust seasoning with salt and additional black pepper as needed. Garnish with fresh parsley and serve hot over steamed white rice or egg noodles.
