Ingredients (Serves 4)
- 1 lb sirloin steak bites, cut into 1 inch pieces, 450 g
- 1 lb cremini mushrooms, halved, 450 g
- 3 cups fresh spinach, loosely packed, 90 g
- 1 tablespoon butter, 14 g
- 1 tablespoon olive oil, 15 ml
- 1 tablespoon fresh sage, finely chopped, or 1 teaspoon dried sage
- 2 garlic cloves, minced
- 1 teaspoon salt, divided, 6 g
- 1/2 teaspoon black pepper, 1 g
- 1/2 teaspoon smoked paprika, optional
- 1 teaspoon lemon juice, optional, for finishing
Step-by-Step Instructions
1. Prep the steak and mushrooms 🔪
Pat the steak bites very dry with paper towels. This helps them sear instead of steam.
Place them in a bowl with 1/2 teaspoon salt, black pepper, and smoked paprika if using. Toss until the steak looks evenly coated.
Halve the mushrooms. Keep them chunky. They will shrink as they cook.
2. Sear the steak until deeply browned 🥩
Heat a large skillet over medium high heat. Add the olive oil.
When the oil looks shiny and moves quickly across the pan, add the steak in a single layer. You should hear a loud sizzle right away.
Let the steak sit without moving for 1 to 2 minutes. Look for browned edges and a deep golden crust on the bottom.
Turn the pieces and cook for another 1 to 2 minutes. The steak should smell savory and roasted, not watery.
Transfer the steak to a plate. It will finish cooking later, so do not overcook it now.
3. Cook the mushrooms in sage butter 🍄
Lower the heat to medium. Add the butter to the same skillet.
When the butter melts and starts to foam, add the mushrooms, remaining 1/2 teaspoon salt, and sage.
Stir well, then spread the mushrooms out. Let them cook for a few minutes before stirring again.
Watch for the mushrooms to release their moisture. The pan may look wet at first. Keep cooking until that liquid evaporates and the mushrooms turn golden brown at the edges.
Your kitchen should smell earthy, buttery, and herbal from the sage.
4. Add garlic for deep flavor 🧄
Add the minced garlic to the mushrooms.
Stir for about 30 seconds, just until the garlic smells warm and fragrant. Do not let it burn. It should smell sweet and savory, not sharp or bitter.
5. Return the steak to the skillet 🔥
Add the steak bites and any juices from the plate back into the skillet.
Toss everything together so the steak gets coated in the sage butter and mushroom juices.
Cook for 1 to 2 minutes, just until the steak is hot and cooked to your liking.
6. Fold in the spinach 🌿
Add the spinach by the handful.
Gently fold it into the hot steak and mushrooms. At first, the pan will look very full. Within a minute, the spinach will soften into glossy green ribbons.
Stop cooking when the spinach looks wilted but still bright green.
7. Finish and serve 🍋
Turn off the heat. Add a small squeeze of lemon juice if you want a brighter finish.
Taste and adjust with a little more salt or black pepper.
Serve warm as is, or spoon it over rice, mashed potatoes, couscous, or toasted sourdough.
Expert Troubleshooting & FAQs
Why is my steak tough?
The steak may have cooked too long, or the pan was not hot enough at the start. Sear the steak quickly over medium-high heat, then remove it from the pan. Add it back only at the end to warm through.
Why are my mushrooms watery?
Mushrooms release a lot of moisture. Give them space in the pan and let the liquid cook off. Do not rush this step. Once the pan dries out, the mushrooms will start to brown and taste much richer.
Can I use another cut of beef?
Yes. Sirloin works well because it is lean, tender, and usually affordable. You can also use ribeye for a richer version or flank steak cut into small pieces. Avoid very tough stew meat unless you plan to cook it much longer.
Serving Ideas
This skillet tastes great with simple sides:
- Brown rice or white rice

Storage and Reheating
Store leftovers in an airtight container in the fridge for up to 3 days.
Reheat gently in a skillet over medium-low heat. Add a splash of water or broth if the pan looks dry. Avoid high heat, because it can make the steak chewy.
