Ingredients
1 lb sirloin steak, thinly sliced against the grain
1 red bell pepper, thinly sliced
1 yellow bell pepper, thinly sliced
1 small red onion, thinly sliced
3 garlic cloves, minced
1/2 tsp red pepper flakes (adjust to taste)
1/3 cup prepared pesto sauce (basil-based) or click for home-made Fresh Pesto Basil Sauce
8 oz noodles (linguine, spaghetti, or rice noodles work well)
2 tbsp olive oil
Salt and freshly ground black pepper, to taste
Optional: grated Parmesan for serving
Instructions
-
Prep the noodles: Cook according to package directions. Drain and set aside, reserving 1/4 cup of pasta water.
-
Sear the sirloin: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add the sliced sirloin, season with salt and pepper, and cook until just browned (about 3–4 minutes). Remove and set aside.
-
Sauté the veggies: In the same skillet, add another tbsp olive oil. Sauté onions and bell peppers until just tender, about 5 minutes. Add garlic and red pepper flakes; cook 1 minute more.
-
Combine: Return the beef to the pan. Add pesto sauce and a splash of pasta water to create a silky sauce. Toss in cooked noodles and mix until well coated.
-
Serve: Plate and top with optional Parmesan and a few extra pepper flakes if desired.
Notes
Tips:
- Slice Against the Grain: For the most tender steak strips, slice your sirloin thinly against the grain.
- Use Pre-Sliced Veggies: Save time by prepping your peppers and onions ahead of time or using pre-sliced from the store.
- Add Pesto Off Heat: Stir in the pesto at the end to preserve its fresh flavor and vibrant green color.
- Adjust Heat: Like it spicy? Add extra red pepper flakes or a dash of hot sauce.
- Make It a Bowl: Serve over rice noodles or in a bowl with spiralized zucchini for a low-carb twist.
- Prep Tip: Cook your noodles in advance and store them in the fridge to make this a lightning-fast weeknight dinner.
