This Vegetarian, Creamy Cajun Pasta is perfect for Autumn, with a creamy, spicy sauce and roasted delicata squash! Each bite is bursting with spicy, smoky flavor, with just the right amount of cheese.
All I’ll say is that this pasta is SO. GOOD. It is one of my most favorite recipes I’ve EVER made. The Cajun spice blend is just elite, I said what I said. Combined with garlic and onions, this pasta is an umami BOMB!
Making it is super simple, too. You roast the delicata squash, which is easy and quick. Then, while that’s roasting, you make the pasta sauce by sautéing the onion, garlic, and spices (so they can bloom). Then comes a little bit of cream and butter. You cook your pasta along with it, so when it’s ready, you take the pasta directly from the pot and put it into the sauté pan with the sauce. Add in a little bit of the pasta water and some cheese, and that’s basically it!
I hope you love this one as I do! After my recipe tests I made it twice more just for dinner within one week 🙈 Enjoy!!

Instructions
- Before making this recipe, read through all of the instructions. At lot of things happen at the same time, so make sure you have a sense of what to do and when to do it!
Delicata Squash
- Preheat the oven to 425 degrees F.
- Cut the ends off your delicata squash, then cut it in half lengthwise. Using a spoon, scoop out the inner seeds and stringy bits (you can save the seeds for another recipe). Then, cut the squash into half-moons about 1/2" thick or so (it doesn't need to be exact).
- Lay the sliced squash on a baking sheet lined with parchment paper. Drizzle over the olive oil, salt, and pepper, and mix. Then, spread the squash back out on the tray so that no pieces are overlapping.
- Bake the squash in the oven for 20 minutes, then take out and stir them around. Make sure after you stir the squash, that you spread them out again, making sure no pieces are overlapping.
- Bake for another 10-15 minutes, until the pieces are fork-tender and just starting to brown on the edges. Be sure to check often close to the end of the cooking time, to prevent overcooking.
- When done, take out from the oven and set aside.
Creamy Cajun Pasta
- Begin the pasta by prepping your aromatics – chop the onions and mince the garlic, then set aside.
- Put a large pot of SALTED water on the stove on high heat, to start warming up to a boil. The water must be salted – add in 2 tsp – 1 tbsp of salt.
- While the water is coming to a boil, add the olive oil to your largest skillet or sauté pan, and bring it medium-low heat. Add in the onion, and sauté for about 2-3 minutes, or until onions are starting to soften. Then, add in the garlic and sauté for another 30 seconds, until fragrant. Turn the heat down to low, if needed, if the garlic starts to brown.
- Then, add in all of the salt and dried spices, and sauté with the onions and garlic for another minute or so. Once the spices have "bloomed" and become fragrant, add in the mustard, tomato paste, and butter. Sauté everything together. Once mixed, add in the cream and mix again. Then, reduce heat to low while you wait to add in the pasta (or turn off heat if your stovetop runs hot).
- At this point, the salted water in the pot should be boiling. Add in 12 ounces of pasta, and stir. Cook the pasta for 2 minutes LESS than the "al dente" time on the pasta box. Before you take the pasta out, carefully remove about 1 cup of the hot, salted pasta water and set it aside.
- Once the pasta has reached 2 minutes less than the "al dente" cooking time, take it out of the pot using a mesh sieve or a slotted spoon, and put it directly into the sauté pan with the cajun cream sauce.
- Once all of the pasta is in the saucepan, bring the heat back up to medium low. Stir the pasta all around in the sauce, adding in a little of the reserved pasta water if need be, to loosen.
- Continue cooking the pasta in the sauce until it is al dente, continuing to add the reserved pasta water to loosen if necessary. When the pasta is at your desired texture, remove from heat, and stir in the grated cheese until melted.
- Top the pasta with the roasted delicata squash, and garnish the pasta with more cheese and fresh parsley, if desired.
- Serve, and enjoy!
Notes
- If the Cajun spice blend you’re using has a lot of salt, you may want to use less than 1/2 tsp of salt in the recipe. Be sure to carefully taste the sauce as you go, making adjustments where needed.
