Step‑by‑Step Instructions for Pumpkin & Mushroom Spaghetti with Crispy Bacon
Step 1: Cook Pasta
Begin by boiling a large pot of salted water over high heat. Once the water reaches a rolling boil, add the spaghetti and cook according to package instructions until al dente, about 8-10 minutes. Before draining, remember to reserve ½ cup of the pasta water to help adjust the sauce’s consistency later.
Step 2: Cook Bacon
In a large skillet, heat over medium heat and add the thick-cut bacon. Cook the bacon until it becomes crispy, usually about 5-7 minutes, turning occasionally to ensure even cooking. Once crispy, transfer the bacon to paper towels to drain, keeping a tablespoon of the rendered grease in the skillet for added flavor.
Step 3: Sauté Mushrooms
Using the same skillet with the reserved bacon grease, add the mushrooms over medium heat. Sauté the mushrooms for 5-7 minutes, stirring frequently, until they are browned and tender. You want them to become golden but not burnt, as this adds an earthy depth to your Pumpkin & Mushroom Spaghetti.
Step 4: Add Garlic
Once the mushrooms are ready, stir in the minced garlic and cook for an additional minute. The garlic should become fragrant and slightly golden. Be careful not to burn it, as burnt garlic can give the dish an unpleasant bitterness. This adds a delightful layer of flavor to the base of your sauce.
Step 5: Combine Sauce Ingredients
To the skillet, mix in the canned pumpkin puree, dried thyme, smoked paprika, nutmeg, salt, and pepper. Stir constantly for about 2-3 minutes until the mixture is well combined and heated through. The creamy pumpkin sauce should appear smooth and vibrant, filling your kitchen with delightful autumn aromas.
Step 6: Finish Sauce
Next, pour in the heavy cream and add the grated Parmesan cheese. Allow the mixture to gently simmer for 2-3 minutes, stirring occasionally, until it thickens slightly. The sauce should be creamy and cohesive, perfectly complementing the earthy flavors of the mushrooms and the savory notes from the bacon.
Step 7: Toss Pasta
Add the cooked spaghetti to the skillet with the creamy pumpkin sauce, using tongs to gently toss and coat the pasta thoroughly. If the sauce is too thick, gradually add reserved pasta water until you reach your desired consistency. This step ensures every strand of spaghetti is perfectly enveloped in the flavorful sauce.
Step 8: Serve
Finally, plate your delicious Pumpkin & Mushroom Spaghetti and top each serving with the crispy bacon pieces and a sprinkle of fresh parsley for garnish. If desired, add extra Parmesan cheese on top. This rich and comforting dish is now ready to be enjoyed, bringing the flavors of fall right to your table!

Expert Tips for Pumpkin & Mushroom Spaghetti
• Creamy Balance: Avoid adding too much heavy cream since pumpkin already provides a naturally creamy base for your sauce.
