If you have trouble eating enough vegetables, this pasta bake is here to save the day. It’s packed to the brim with nutrient-rich veggies, Italian chicken sausage, and creamy goodness. Everything comes together in one pan (other than cooking pasta) and one serving has 20 grams of protein with just 265 calories!

Italian Sausage Pasta Bake Recipe Walkthrough
You’ll find a printable recipe card at the bottom of this post, but the walkthrough below will cover ingredient notes and tips worth reading before diving in.
Step 1: Sauté Mushrooms, Zucchini, and Red Bell Pepper for 5 Minutes

Don’t be afraid to let the veggies develop some color here. Add them to the hot olive oil, toss/stir, and let them hang out for most of the 5 minutes.

That said, you shouldn’t need to deglaze the pan or have any burning here. If you smell charring, stir and consider reducing the heat a smidge.
Ingredient notes for step 1: Feel free to use other types of mushrooms. To save prep time, you can probably find all three of the veggies here pre-sliced. You can also omit any of the veggies in this recipe. Just know the serving sizes and nutrition info will be affected.
Step 2: Add Garlic, Cherry Tomatoes, and Chicken Sausages and Sauté Another 5 Minutes

If you have some crispy bits stuck to the bottom of your pan at this point, you can use a bit of red wine vinegar (or any liquid) to deglaze the pan before continuing.
Give everything a stir and let it hang out again. The cherry tomatoes should begin to wrinkle around the 5-minute mark. You want them to stay mostly whole so avoid completely mashing them with your spatula.

Ingredient notes for step 2: I used two different types of chicken sausage from Trader Joe’s (garlic herb and spicy Italian). Though you could use their sweet Italian to reduce the spice or any other type of fully cooked sausage in your pasta bake. Check out my 5-ingredient chicken sausage pasta for another recipe to make with leftover sausage. For the cherry tomatoes, I used a medley, but you could probably do any cherry or grape tomato option.
Step 3: Add a Marinara, Light Alfredo Sauce, and Pasta of Your Choice

Turn off the heat before adding the sauces. If you need to deglaze again, a little marinara should do the trick. Give everything another stir before adding cooked pasta.
Keep the pan over the burner after turning it off. You want to keep everything warm in case you need to wait on your pasta to finish cooking.

Stir the pasta in and you’re ready to top with cheese and bake. Almost done!

Ingredient Notes for Step 3
If you’ve tried my Cajun Sausage Pasta Bake, you’ll be familiar with the light alfredo and marinara combo. There are dairy-free alfredo options out there, but you could also omit and use more marinara in its place.
Other alfredo replacements might be a low fat ricotta like I used in my Beef Cannelloni recipe or the blended cottage cheese and alfredo sauce I used to make my high protein lasagna.
For the pasta, you could use a lower carb option like the Banza chickpea shells I used for my Taco Pasta Bake.
Step 4: Top with Shredded Mozzarella and Parmigiano Reggiano and Bake for 15-20 Minutes

Ingredient notes for step 4: Use freshly grated cheese if possible. Regular parmesan is a fine substitute for the parmigiano reggiano, but the later packs a bit more flavor in the small amount used (in my opinion). Feel free to use other pasta-friendly cheese options. And in case you’re wondering, cutting the mozzarella in half to save some calories and fat should work fine.

Bonus tip: Serve this pasta bake with some of my parmesan bread twists or cheesy garlic air fryer bread (you can bake it, too)!

If using Banza, do I still cook it 6min or does that change?

6 minutes should work for Banza as well.

I make this at least once a month. It’s that good! I like to add yellow summer squash to add a little more variety and color.

As are all of your recipes, this quick, easy and delicious! Since we wouldn’t use the jarred Alfredo sauce for anything else, I bought the spice packet, mixed it with fat free milk- certainly a thinner consistency, but the flavors were there and lower in fat. This is a staple in our house!

Made this again today with modifications. I used a jar of roasted red peppers instead of bell pepper, plant based pasta (pea pasta- extra protein), a cup of reduced fat mozzarella and forego the Parmesan, and I double the chicken sausage. I mix the cheese into it instead of baking on top. Can skip the cheese- great option for anyone dairy free. Love that you can make in one pot. I added protein and made it 6 instead of 8 servings to better meet my macro needs.
