Pumpkin & Mushroom Spaghetti Ingredients
For the Pasta
• Spaghetti – This main carbohydrate source can be swapped for whole wheat or gluten-free pasta for added nutrition.
For the Sauce
• Thick-Cut Bacon – Adds saltiness and a delightful crunch; substitute with turkey or plant-based bacon for a lighter option.
• Olive Oil (optional) – Used for sautéing; can be omitted or replaced with butter for extra flavor.
• Mushrooms (sliced) – Provide an earthy base and umami flavor; feel free to use any variety, but avoid overcrowding the pan while sautéing.
• Garlic (minced) – This aromatic ingredient enhances the dish’s overall flavor; fresh garlic is always best for a punch of taste.
• Canned Pumpkin Puree – Forms the creamy sauce base; for a fresh twist, use roasted pumpkin as a substitute.
• Dried Thyme – Offers a subtle herbal note; fresh thyme can also substitute beautifully.
• Smoked Paprika – Adds a depth of smoky flavor; regular paprika can work in a pinch.
• Nutmeg (optional) – This warm spice enhances sweetness; you can skip it if you don’t have it on hand.
• Salt & Pepper – Essential for seasoning; adjust according to your taste preferences.
• Heavy Cream – Creates a rich texture for the sauce; use milk or dairy-free cream for a lighter version.

Step‑by‑Step Instructions for Pumpkin & Mushroom Spaghetti with Crispy Bacon
Step 1: Cook the Spaghetti
Begin by boiling a large pot of salted water. Add spaghetti and cook according to package instructions until al dente, usually around 8-10 minutes. As the noodles cook, reserve ½ cup of pasta water for later use. Once al dente, drain the pasta and set it aside, ensuring not to rinse to keep the starch that helps the sauce adhere.
Step 2: Prepare the Bacon
In a large skillet, add thick-cut bacon and heat over medium. Cook the bacon for about 5-7 minutes, turning occasionally until crispy and golden brown. Once cooked, transfer the bacon to a paper towel-lined plate to drain. Allow it to cool briefly, then chop it into small, crispy bits that will enhance the flavor of the Pumpkin & Mushroom Spaghetti.
Step 3: Sauté the Mushrooms
With the skillet still on medium heat, drain excess bacon grease but leave about 1 tablespoon in the pan for flavor. If needed, add a little olive oil. Once the oil is hot, add sliced mushrooms. Sauté for about 5-7 minutes until they become nicely browned and tender, stirring occasionally to ensure even cooking and prevent steaming.
Step 4: Add Garlic and Spices
Once the mushrooms are golden, add minced garlic to the pan, cooking for an additional minute until fragrant. Stir vigorously to incorporate the garlic into the sautéed mushrooms. Then, sprinkle in dried thyme, smoked paprika, salt, and pepper, allowing the spices to infuse their flavors into the mixture as you remove the pan from the heat.
Step 5: Combine with Pumpkin
Return the pan to low heat and stir in canned pumpkin puree. Mix well, ensuring that the pumpkin blends with the mushrooms and spices. Allow this mixture to cook for about 2-3 minutes, stirring continuously. This step creates a creamy base that beautifully enhances the Pumpkin & Mushroom Spaghetti, making it rich and flavorful.
Step 6: Create the Sauce
Pour in the heavy cream and add grated Parmesan cheese to the pumpkin mixture. Increase the heat slightly to let the sauce simmer for 2-3 minutes, allowing it to thicken. Keep stirring until the cheese completely melts and integrates into the creamy sauce, making it velvety and inviting.
Step 7: Toss the Pasta
Once your sauce has thickened, reduce the heat to low and add the drained spaghetti. Gently toss the pasta in the sauce, ensuring every strand is coated evenly. If the sauce appears too thick, incorporate some of the reserved pasta water to achieve your desired consistency, resulting in a perfect Pumpkin & Mushroom Spaghetti with Crispy Bacon.
Step 8: Serve and Garnish
Now it’s time to plate your delightful dish! Serve the spaghetti warm, topping it generously with the reserved crispy bacon bits and a sprinkle of chopped fresh parsley for color. Add extra Parmesan cheese if desired to elevate the presentation. Enjoy the cozy flavors of this perfect fall-inspired meal!
