Ingredients
Gather ’round, friends, because here’s what you’ll need to create this bowl of autumnal bliss. Don’t be intimidated by the list; most of these are pantry staples or easy-to-find treasures!
- 1 tablespoon butter: For starting our flavor base.
- ½ cup chopped onion: The humble onion, our foundational flavor builder.
- 3 cloves garlic, minced: Because what good dish doesn’t start with garlic?
- 1 cup chopped carrots (about 4 medium): Adds a lovely sweetness and beautiful color.
- 1 (28-ounce) can crushed tomatoes: The backbone of our sauce.
- 1 (15-ounce) can pumpkin puree (not pumpkin pie filling): This is key for that creamy, earthy sweetness. Make sure it’s 100% pumpkin!
- 2 to 3 cups diced butternut squash (about 340 grams): This is the star of the harvest show! It gets so tender and delicious.
- ½ cup chicken broth or stock: Adds depth and helps everything simmer beautifully.
- 1 tablespoon granulated or brown sugar: Just a touch to enhance the natural sweetness of the veggies.
- 1 teaspoon salt: To bring out all those wonderful flavors.
- 1 teaspoon dried parsley: A classic herb that pairs perfectly.
- ½ teaspoon Italian seasoning: A little blend of Mediterranean sunshine!
- ¼ teaspoon black pepper: For a gentle kick.
- Pinch cayenne pepper: Optional, but I love a tiny whisper of heat to make everything pop!
- ½ cup half and half or cream (or milk): To make it lusciously creamy and rich.
How to Make It
Alright, let’s get cooking! This is where the magic happens, and trust me, it’s a joy to make.
- Melt the Butter: Grab your favorite large pot or Dutch oven and melt that butter over medium heat. It’s the first cozy step!
- Sauté the Onion: Toss in your chopped onion and let it soften up. This usually takes about 5 minutes. You want them nice and translucent, not browned.
- Add the Garlic: Now, stir in your minced garlic. Cook for just 1 minute more until it smells absolutely amazing. Be careful not to burn it!
- Tenderize the Carrots: Add your chopped carrots and let them cook for about 5-7 minutes, giving them an occasional stir. We want them to start getting a little tender.
- Combine the Stars: Pour in the crushed tomatoes and the pumpkin puree. Give it a good stir to combine all those wonderful ingredients.
- Add the Harvest Goodness: Now for the rest of the flavor party! Add your diced butternut squash, chicken broth, sugar, salt, parsley, Italian seasoning, black pepper, and that optional pinch of cayenne. Stir it all together.
- Simmer to Perfection: Bring the mixture to a gentle simmer. Once it’s bubbling slightly, reduce the heat to low, pop on a lid, and let it cook for 20-25 minutes. Give it a stir every now and then to make sure nothing is sticking, and you’ll know it’s ready when the butternut squash is perfectly tender when you poke it with a fork.
- Get Creamy: Stir in your half and half or cream until everything is beautifully blended and the sauce has that lovely, rich color.
- Serve with Love: Ladle this warm, comforting sauce over your favorite cooked pasta. A sprinkle of Parmesan cheese on top is practically mandatory, in my humble opinion!
Substitutions & Additions
This recipe is wonderfully adaptable. Feel free to play around and make it your own!
- Squash Swap: If you can’t find butternut squash, acorn squash or even sweet potatoes would be delicious alternatives.
- Broth Boost: Vegetable broth works just as well if you prefer to keep it vegetarian.
- Spice it Up: For a heartier flavor, a pinch of nutmeg or cinnamon can add a lovely warmth. A bay leaf simmered in the sauce and removed before serving is also a great addition.
- Herbal Notes: Fresh herbs like sage or thyme would be a delightful addition. Add them in the last 5-10 minutes of simmering.
- Creamy Alternatives: If you don’t have half and half or cream, you can use whole milk for a lighter sauce, or even a splash of coconut milk for a dairy-free option.

Tips for Success
A few little pointers to make your Harvest Pasta Sauce absolutely perfect every time.
- Butternut Squash Prep: Pre-cut butternut squash is a lifesaver if you’re short on time. Just be sure it’s pure squash and not a pre-made mix.
- Don’t Rush the Sauté: Taking the time to soften the onions and carrots builds a really nice flavor base for the sauce.
- Taste and Adjust: Always taste your sauce before serving! You might want a little more salt, a touch more sugar, or another pinch of seasoning.
- Prep Ahead: You can chop your onions, garlic, and carrots a day in advance and store them in airtight containers in the refrigerator.
- Freezing Friendly: This sauce freezes beautifully! Let it cool completely, then portion it into freezer-safe containers or bags. It’s a lifesaver for future quick meals.
How to Store It
Leftovers are the best, aren’t they? Once cooled, you can store your Harvest Pasta Sauce in an airtight container in the refrigerator for up to 3-4 days. It’s also fantastic for freezing! Portion it into freezer-safe containers or bags, and it should keep well in the freezer for about 2-3 months.
FAQs
Got a question? I’ve got answers!
Can I make this sauce vegan?
Absolutely! Simply swap the butter for olive oil or vegan butter, and use vegetable broth instead of chicken broth. For the creamy finish, use full-fat coconut milk or a good quality unsweetened plant-based cream. Enjoy!
What kind of pasta is best for this sauce?
This sauce is wonderfully versatile! It’s delicious over classic spaghetti, linguine, or fettuccine. It also clings beautifully to fun shapes like rotini or penne, ensuring you get that yummy sauce in every bite.
Can I blend the sauce for a smoother texture?
Yes, you can! If you prefer a smoother sauce, you can carefully transfer the cooked sauce (making sure the butternut squash is very tender) to a blender or use an immersion blender right in the pot. Blend until you reach your desired consistency. Be cautious when blending hot liquids!
