Key Ingredients & Substitutions
Fettuccine: This broad pasta works great in this dish, holding onto the creamy sauce well. If you want to mix it up, try using whole wheat pasta or spaghetti for a different texture.
Pumpkin Puree: Canned pumpkin puree is convenient and works well. If you have fresh pumpkin, roast and blend it to make your own puree. You’ll get a fresher flavor, but it takes a bit more time!
Heavy Cream: This gives the sauce its richness. For a lighter option, you can substitute half-and-half or even coconut cream for a dairy-free version. Just know that the flavor will change slightly.
Parmesan Cheese: Freshly grated Parmesan adds the best flavor. If you need a substitute, Pecorino Romano or nutritional yeast for a vegan option can work well.
Nutmeg: Just a pinch adds warmth and depth to the sauce. Feel free to skip it if you don’t have any on hand, but consider adding a dash of cinnamon for a new twist!
How Do I Make This Sauce Creamy and Smooth?
Getting that perfect creamy texture is key for Pumpkin Alfredo Sauce. Start by slowly whisking in the heavy cream into the pumpkin mixture. Make sure it’s heated gently—too high of heat can separate the cream.
- Use medium heat when melting the butter and sautéing the garlic. It helps in preventing burning.
- Whisk constantly while adding cheese to ensure it melts seamlessly into the sauce.
- If your sauce is too thick, add reserved pasta water a tablespoon at a time. This helps loosen it while keeping the flavor strong.

Delicious Pumpkin Alfredo Sauce with Fettuccine
Ingredients You’ll Need:
- 12 oz fettuccine pasta
- 2 tbsp unsalted butter
- 3 cloves garlic, minced
- 1 cup pumpkin puree (canned or fresh)
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 1/4 tsp ground nutmeg
- Salt and freshly ground black pepper, to taste
- 1/4 cup fresh parsley, chopped (for garnish)
How Much Time Will You Need?
This Pumpkin Alfredo Sauce with Fettuccine takes about 30 minutes from start to finish! You’ll spend about 10 minutes cooking the pasta and around 20 minutes preparing the sauce and combining everything. It’s a quick and yummy meal perfect for any night!
Step-by-Step Instructions:
1. Cook the Fettuccine:
Start by cooking the fettuccine pasta according to the package instructions until it’s al dente, meaning it’s still slightly firm when bitten. Once it’s done, drain the pasta, but remember to reserve about 1/2 cup of the pasta water just in case you need it later!
2. Make the Sauce Base:
In a large skillet or saucepan, melt the 2 tablespoons of unsalted butter over medium heat. Be patient—let it melt gently without sizzling too much. Then, add the minced garlic and sauté it for about a minute. You want it fragrant but not browned!
3. Add the Pumpkin:
Once the garlic is nice and aromatic, stir in the pumpkin puree. Mix it well with the garlic butter; this creates a lovely base for your sauce.
4. Create the Creamy Mixture:
Now, pour in the heavy cream and whisk until the sauce is nice and smooth. Allow it to heat through gently—just be careful not to let it boil, as we want a creamy texture!
5. Incorporate Cheese and Seasonings:
Add the grated Parmesan cheese and ground nutmeg to your sauce. Stir constantly until the cheese melts completely and the sauce transforms into a rich, creamy delight. Taste and season with salt and freshly ground black pepper until it’s just right for you.
6. Combine Pasta and Sauce:
Gently add the cooked fettuccine to the sauce, tossing everything together so the pasta is fully coated. If you find the sauce is a bit too thick, don’t worry! Just add a little bit of the reserved pasta water, a tablespoon at a time, until it reaches the desired consistency.
7. Serve and Enjoy:
Dish up your delicious Pumpkin Alfredo Fettuccine immediately! Garnish with a sprinkle of freshly chopped parsley and an extra dash of black pepper if you like. Enjoy your comforting meal!

Can I Use Fresh Pumpkin Instead of Canned Puree?
Absolutely! If you prefer fresh pumpkin, just roast it until tender, then blend it into a smooth puree. It will add a fresher flavor, but you’ll need to allow extra time for cooking and blending.
What If I Don’t Have Heavy Cream?
If you don’t have heavy cream, you can substitute it with half-and-half, whole milk, or even coconut cream for a dairy-free option. Keep in mind that the sauce may be a bit lighter in texture with these alternatives.
How Long Can I Store Leftover Pumpkin Alfredo Sauce?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently on the stove over low heat, adding a splash of cream or water to loosen it up if necessary.
Can I Add Other Vegetables to This Sauce?
Definitely! Feel free to add cooked spinach, kale, or sautéed mushrooms for an extra nutritious boost. Just make sure they’re cooked before mixing them into the sauce for the best texture and flavor.
