Ingredients
- 12 oz penne pasta
Penne pasta is ideal for this bake because its ridged surface helps capture the creamy sauce, ensuring a rich flavor in every bite. - 2 tbsp olive oil
Olive oil adds richness and depth to the dish, serving as an essential ingredient for sautéing the mushrooms and ensuring they develop a flavorful, golden color. - 1 large onion, diced
Onions introduce sweetness and a robust base flavor that enhances the overall taste profile of the pasta, creating a savory backdrop for the cream and mushrooms. - 4 cups mushrooms, sliced (cremini or button)
Mushrooms are the star of this dish, providing a hearty and umami-rich component that pairs beautifully with the cream, creating a deeply satisfying experience. - 3 cloves garlic, minced
Garlic contributes a fragrant, aromatic quality to the dish, elevating the flavors of the mushrooms and tying all the ingredients together. - 1 cup heavy cream
Heavy cream is crucial for achieving the rich, velvety sauce that makes this bake so comforting; it coats the pasta beautifully and adds a luxurious mouthfeel. - 1 cup grated Parmesan cheese
Parmesan not only enhances the dish's flavor with its saltiness and nuttiness but also helps create a deliciously cheesy crust when baked. - 1 tsp dried thyme
Thyme brings a subtle earthiness to the pasta bake; its aromatic notes complement the mushrooms and enrich the overall flavor. - Salt and pepper to taste
These staples enhance and balance the flavors throughout the dish, making sure each component shines through. - 1/2 cup breadcrumbs
Breadcrumbs add a delightful crunch to the top of the pasta bake, providing a contrast to the creamy texture beneath and enhancing the dish visually.
Directions & Preparation
Step 1: Preheat the oven to 375°F (190°C).
Preheating the oven is a crucial first step as it ensures that your pasta bake cooks evenly and sets to perfection once placed inside. This initial heat will help the baking process begin immediately, preventing any overcooking of ingredients that might occur if the dish is placed in a cold oven.
Step 2: Cook the penne pasta according to package instructions until al dente; drain and set aside.
Cooking the pasta until al dente preserves its structure, allowing it to hold up during baking. Overcooking the pasta beforehand can lead to mushy results, and since it continues to cook in the oven, achieving the right texture at this stage is vital for a successful bake.
Step 3: In a large skillet, heat olive oil over medium-high heat; add onions and sauté until translucent, about 4-5 minutes.
Sautéing the onions in olive oil enhances their natural sweetness and builds the foundation for the dish's flavor. Cooking them until they are translucent ensures they are soft and flavorful, avoiding any raw onion taste in the final dish.
Step 4: Add sliced mushrooms and garlic to the skillet; cook until mushrooms are tender, about 5-7 minutes.
This step is critical for developing the rich, savory flavors of the mushrooms. As they cook, they release moisture, which helps to concentrate their flavor and create a delightful base for the creamy sauce.
Step 5: Stir in the heavy cream, thyme, salt, and pepper; simmer for 2-3 minutes to thicken slightly.
Allowing the cream to simmer with the sautéed vegetables integrates all the flavors beautifully while thickening the sauce slightly. This step ensures that the pasta will be coated with a creamy, flavorful sauce once baked.
Step 6: Combine the cooked pasta with the mushroom cream sauce; mix well to coat.
In this step, ensuring the pasta is thoroughly mixed with the sauce is essential, guaranteeing that each bite is filled with the delicious mushroom flavor. A fully combined mixture is also crucial for even cooking during the baking process.
Step 7: Transfer the pasta mixture to a greased baking dish; top with grated Parmesan and breadcrumbs.
Arranging the mixture in a baking dish creates a beautiful layer for even baking. Topping with parmesan and breadcrumbs ensures a crispy and cheesy crust, which is a delightful contrast to the creamy pasta underneath.
Step 8: Bake for 25-30 minutes or until golden and bubbly.
Baking the pasta until golden brown not only enhances the flavor through caramelization but also ensures a pleasing texture. Watching for the bubbling sauce signals that the dish is cooked through and ready to be served.
Step 9: Let it cool for a few minutes before serving; garnish with fresh herbs if desired.
Allowing the pasta bake to sit briefly after baking helps it set, making it easier to serve. Garnishing with fresh herbs adds a pop of color and brightness, elevating the overall presentation and flavor.

Embracing Seasonal Mushrooms
The choice of mushrooms can significantly impact the flavor profile of your creamy mushroom pasta bake. While cremini and button mushrooms are popular, consider exploring seasonal varieties such as shiitake or oyster mushrooms for a unique twist. Each type can bring its own distinctive taste and texture; for instance, shiitake mushrooms add a rich, meaty flavor that complements the creamy sauce beautifully.
Customizing Your Pasta Bake
One of the joys of making a pasta bake is the ability to tailor it to your preferences. Aside from mushrooms, feel free to add ingredients like spinach, sun-dried tomatoes, or even artichokes. These additions not only enhance the nutritional value but also introduce fresh flavors and colors to the dish. Just be sure to adjust the cooking time slightly if you include ingredients that need more cooking.
Pairing Suggestions
To round out your meal, consider pairing your creamy mushroom pasta bake with a simple salad or garlic bread. A light, crisp green salad complements the richness of the dish, offering a refreshing contrast. Garlic bread provides a crunchy, buttery accompaniment that’s perfect for scooping up the creamy pasta, making for a satisfying and complete dining experience.
FAQs
What can I do if my sauce is too thick?
If your sauce turns out too thick, simply stir in a splash of vegetable or chicken broth or some additional cream to reach your desired consistency.
How can I make this dish spicier?
For a spicier kick, add a pinch of red pepper flakes during the sauté stage or incorporate sliced jalapeños with the mushrooms.
Can I use a different type of cheese instead of Parmesan?
Yes, feel free to experiment with other cheeses like mozzarella for a meltier texture or Gruyère for a nutty flavor profile.
What if my pasta is sticking together after cooking?
If your pasta sticks, ensure you stir it immediately after draining and lightly coat it in olive oil to prevent clumping.
Can I add protein to this dish?
Absolutely! Shredded chicken, cooked sausage, or sautéed shrimp can be added to the pasta for a protein boost, enhancing the dish's heartiness.
What if I overcook my pasta?
If your pasta is overcooked, it may become mushy. Next time, aim for al dente and reduce the cooking time slightly for better results.
