Directions

  1. Boil salted water in a medium saucepan and cook the spaghetti until al dente, about 8–10 minutes.
  2. While the pasta cooks, heat a skillet over medium-high heat.
  3. Add a small amount of oil, then the mushrooms; season with salt and pepper and cook until softened, 4–5 minutes.
  4. Stir in the spinach, Alfredo sauce, sun-dried tomato pesto, and a splash of water; heat through, stirring often, until warmed and simmering gently as the pasta finishes.
  5. Drain the pasta and add it to the skillet; toss to coat with the sauce, then remove from heat and divide between bowls or plates.

Two tips

  • Prep the mushrooms and spinach ahead if you’re short on time, storing them in the fridge until you’re ready to cook.
  • Finish with a light drizzle of olive oil at serving for a glossy finish and extra flavor.
