Why You’ll Love This Recipe For Spaghetti Squash with Amatriciana Sauce
The Bucatini Amatriciana we had on a recent trip to Italy was unforgettable. It blew us away with its flavorful simplicity. The rich slow cooked and salty pork flavor, the hit of hot pepper, the thick tomato sauce cooked right into the al dente noodles. The sharp Pecornio! Total perfection!
Today, I decided it would be a fun twist to serve the sauce with spaghetti squash instead of pasta.
Recipe Highlights
- The recipe is made with grocery store staples. No special trip to the meat market to find guanciale.
- The sauce is quick cooking and very simple to prepare!
- I cooked the spaghetti squash in the microwave so the whole meal comes together in only 30 minutes!
- Much lower in carbs and calories than semolina or wheat pasta.
Ingredient Notes
- Spaghetti Squash: You’ll need one large squash, halved, seeded and roasted
- Bacon: Uncured bacon is the best but you could also use pancetta
- Extra-virgin olive oil: Since this is an Italian-style recipe I would recommend sticking with olive oil
- Other veggies: Crushed tomatoes and onion for the sauce
- Seasonings: Salt, chopped parsley and red pepper flakes
- Cheese: Pecorino or Parmesan grated over top
How to Make This Spaghetti Squash with Amatriciana Sauce
Step 1: Prep spaghetti squash
Place the spaghetti squash in a 9×11-inch baking dish, cut side down. Pour one cup of water into the pan. Cover with a layer of parchment or wax paper. Cover with plastic wrap.
Step 2: Microwave spaghetti squash
Microwave until the spaghetti squash pulls apart into tender threads when tested with a fork, 16 to 20 minutes.
Step 3: Cook bacon
Meanwhile, place bacon in a large skillet and set over medium heat. Cook, stirring often until the bacon is browned and crispy, 6 to 8 minutes. Remove the bacon from the skillet with a slotted spoon and transfer it to a paper towel-lined plate. Pour the fat off into a dish or can.
Step 4: Cook onion
Return the skillet to medium heat, and add oil and red pepper flake. Heat for about 20 seconds. Add onion, and stir to coat with the oil and pepper flake. Continue cooking, stirring occasionally, until the onion is softened and starting to brown, 5 to 7 minutes.
Step 5: Simmer tomato sauce
Add tomatoes and salt and bring to a simmer, stirring often. Simmer until the sauce has thickened slightly, about 5 minutes.
Step 6: Add squash to sauce
When the squash is tender, carefully remove the cover, and transfer the squash to a cutting board with tongs. Scrape spaghetti squash out of the shell with the forks. Add the squash and the reserved bacon to the sauce and simmer for one minute.
Step 7: Garnish & serve
Serve the spaghetti squash topped with pecorino and parsley.
FAQs and Expert Tips
Yes absolutely. If you want the sauce but not the spaghetti squash, you could add regular wheat pasta or zucchini noodles instead.
You want to add the bacon to a cold skillet so that the fat renders off during the cooking process and coats the pan. This prevents the bacon from sticking to it! Also, remember not to overcrowd the skillet as it will prevent even browning.
The sauce can be made a day in advance and stored in an airtight container until ready to use. The squash can also be roasted a day in advance. Once ready to serve, combine the sauce and scraped out spaghetti squash in the skillet and simmer to heat.
You can store this spaghetti squash recipe in an airtight container in the fridge. It’ll stay good for 3 to 4 days.

Thank you Brynn. I bought it at an antique store. I am always on the look out for props. Especially ones like this with a bit of character. Glad you noticed. And thanks!
So many things I love about this…first of all, I love that your sister’s dishes were all the ones with the “simplest ingeredients”. Isn’t that always the case that the simplest dishes are the best? I love that you adapted this to the home cook and use bacon…and you tossed it over spaghetti squash! I’ll be making this dish for sure!
Dish looks amazing! Simple and beautiful.
My husband and I usually have a friendly competition of who ordered the best dish- He did order this dish at least 3 times when we were in Italy this summer- Pinning so I can relive our trip!
We love Vermont Smoke and Cure — everything is better with bacon. I wonder what Italians think of gluten free eating.
