A rich and creamy pasta dish loaded with tender tortellini, sautéed mushrooms, and fresh spinach. Ready in just 20 minutes, this simple yet flavorful recipe is perfect for weeknight dinners or easy meal prep.
Prepare the Tortellini: Start by bringing a medium-sized pot of salted water to a gentle boil over high heat. Once boiling, carefully add the cheese tortellini. Stir occasionally to prevent them from sticking together. Cook according to the package instructions until the pasta is al dente, usually about 3–5 minutes. Once cooked, drain the tortellini and set them aside, reserving a small cup of the pasta water in case you want to loosen the sauce later.
Heat the Olive Oil: While the tortellini is cooking, place a large skillet over medium-high heat and add the tablespoon of olive oil. Allow the oil to warm for about 30 seconds until it becomes shimmering but not smoking. This step ensures the vegetables cook evenly and absorb the flavors of the oil.
Sauté the Aromatics: Add the diced yellow onion to the hot skillet and sauté for about 2–3 minutes until it begins to soften and become translucent. Next, add the minced garlic and cook for an additional 30–60 seconds, stirring constantly to prevent burning. This combination creates the aromatic base that gives the dish its rich, savory flavor.
Cook the Mushrooms: Introduce the sliced portabella mushrooms to the skillet. Stir to coat them evenly with the oil, onions, and garlic. Allow them to cook undisturbed for 2–3 minutes to develop a slight golden color, then stir occasionally until they are tender and have released their natural juices, about 5 minutes total. Season the mixture with salt, black pepper, and red pepper flakes if using. Taste and adjust the seasoning as needed.
Wilt the Spinach: Add the fresh baby spinach to the skillet in small handfuls, stirring gently as you go. The spinach will begin to wilt almost immediately, turning a vibrant green and reducing in volume. Continue cooking and stirring for about 3 minutes, ensuring that all the leaves are evenly coated with the flavorful mushroom and onion mixture.
Incorporate the Cream: Reduce the heat to low to prevent the cream from boiling. Pour in the heavy cream gradually, stirring continuously to create a smooth and velvety sauce. Allow the cream to warm through and thicken slightly, about 2–3 minutes. Be careful not to let it boil, as this can cause separation.
Add Parmesan Cheese: Sprinkle the grated Parmesan cheese over the cream sauce, stirring continuously to melt it completely. This step enriches the sauce, giving it a luscious, silky texture and a savory depth of flavor. Taste the sauce and adjust salt and pepper as needed.
Combine Pasta and Sauce: Gently fold the cooked tortellini into the skillet, making sure each piece is coated with the creamy mushroom-spinach sauce. If the sauce feels too thick, add a small splash of the reserved pasta water to achieve your desired consistency. Allow the pasta to heat together with the sauce for 1–2 minutes so that the flavors meld perfectly.
Serve Warm and Garnish: Transfer the creamy tortellini to serving plates or a large serving dish. For added flavor and presentation, sprinkle extra Parmesan cheese on top or a pinch of freshly ground black pepper. Serve immediately while warm, enjoying the rich, creamy texture paired with tender pasta and flavorful vegetables.
Notes
Use fresh, high-quality cheese tortellini for the best texture and flavor; frozen tortellini works fine but may need an extra minute of cooking.
When sautéing mushrooms, avoid overcrowding the pan to ensure they brown nicely instead of steaming.
For extra richness, try substituting half-and-half or a light cream for heavy cream, though the sauce will be slightly less thick.
Always taste and adjust seasonings gradually—salt, pepper, and red pepper flakes can vary in intensity.
The dish can be made vegetarian-friendly, but ensure your Parmesan cheese is free from animal rennet if serving strict vegetarians.
