Boil a large pot of water. Add a generous pinch of salt, followed by the pasta, and cook to al dente, according to package directions. Drain and set aside.
8 ounces penne
While the pasta cooks, melt the butter in a large skillet set over medium-high heat. Add mushrooms and cook for 3-4 minutes, until tender and well-browned. Add garlic and cook for 30-60 seconds more, just until fragrant. Transfer mushrooms to a plate and set aside. (It’s fine if some of the garlic comes with the mushrooms and some stays in the skillet.)
2 Tablespoons butter, 6-8 ounces sliced mushrooms, 2-3 cloves garlic
Add tomato sauce, tomato paste, broth, Italian seasoning, and red pepper flakes to the skillet. Stir into a smooth sauce and let simmer for 1-2 minutes, then reduce heat to medium and stir in the cream. Simmer for another 2-3 minutes, until it’s as thick as you like. Season with salt and pepper to taste. (I start with 1/4 teaspoon salt and 8-10 cranks pepper.)
1 (14 ounce) can tomato sauce, 2 Tablespoons tomato paste, 1/2 cup chicken or vegetable broth, 1/2 teaspoon Italian seasoning, 1/4-1/2 crushed red pepper flakes, 1/4 cup cream, kosher salt and black pepper
Stir chopped tomatoes and baby spinach into the sauce, followed by the mushrooms and any juices from the plate.
2 Roma tomatoes, 2 cups fresh baby spinach
Add drained pasta, toss well, and serve with generous sprinkles of Parmesan.
