Creamy vegetarian Tortellini Casserole is packed with veggies and coated in a light, tasty cream sauce.

Pair this dish with a light side like this mandarin orange salad or quick Italian salad.

Tortellini Casserole

This casserole is one of our favorites for a lighter dish that feels like total comfort food. It’s packed with veggies, which add a wonderful freshness — something you don’t often find when the word “casserole” is included.

Tortellini Casserole is simple and quick to make; the veggie prep is nothing too time consuming. And one of the best things about this casserole is how easy it is to customize to your personal preference! The veggies can be swapped out and if you’d like to add in some protein, that can be done as well. More details below!

Cooking the tortellini and veggies, adding everything to a casserole, and pouring cream sauce over it.

Tortellini Casserole variations

  • Swap veggies: If you aren’t sure about some of the veggies in this casserole, swap them out for equal amounts of another veggie you do enjoy. Other ideas that would work well:
    • chopped broccoli florets (boil for 2 minutes with the tortellini)
    •  summer squash for zucchini (sauté it with the mushrooms)
    • diced onion and/or garlic (sauté in the skillet before adding in the mushrooms, squash, and peppers)
    • sweet peppers for a green bell pepper
  • Add in meat: To add in some protein, I recommend tossing in some shredded or chopped rotisserie chicken. Other alternatives:
    • chop a small chicken breast or a few thighs, sauté with salt, pepper, and a few seasonings, and add into the dish. (I would not bake the sautéed chicken, because it will dry out. Instead, stir it into individual portions).
    • leftover chopped grilled chicken. Again, stir it into individual portions instead of baking.
  • Cheese: We love freshly grated Parmesan cheese on top, but if you’d prefer a different cheese, try a sharp Cheddar or Italian blend instead.
  • Add some basil pesto: We make pesto all the time and the last few times we’ve made it, I’ve had some pesto lingering in the fridge — it’s delicious in this tortellini casserole! If you love pesto and have some lying around, try it!
  • Lighten up the sauce: The sauce is fairly light tasting (it’s not a heavy cream sauce), but if you’d like to lighten it even more, use Neufchâtel cheese instead (see quick tip below!)

Quick Tip

Neufchâtel is sometimes labeled “1/3 less fat than cream cheese.” Cream cheese and Neufchâtel cheese are extremely similar, but the Neufchâtel keeps this sauce on the lighter side.

Tortellini Casserole

This creamy vegetarian Tortellini Casserole is loaded with tender tortellini and packed full of colorful veggies, all smothered in a light, flavorful cream sauce.
Prep Time: 25 minutes
Cook Time: 25 minutes
Total Time: 50 minutes
Servings: 6 servings

Equipment

  • Casserole dish 9 x 13-inch
  • Large pot
  • Small pot

Ingredients 
 

  • Cooking spray
  • 1 (19-ounce) package cheese-filled tortellini
  • 2 tablespoons olive oil

Veggies

  • 1 cup sugar snap peas
  • 1 cup sliced carrot 1 medium carrot
  • 1 cup sliced baby bella mushrooms
  • 3/4 cup sliced mini sweet bell peppers
  • 1 cup sliced and halved summer squash
  • 1 cup halved cherry tomatoes
  • 1 cup frozen corn

Creamy base

  • 1-1/2 tablespoons unsalted butter
  • 1-1/2 tablespoons flour
  • 1/3 cup vegetable stock or broth
  • 1 cup milk 1%, 2%, or whole milk
  • 1/2 teaspoon roasted garlic powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 teaspoon dried basil
  • 1 teaspoon Italian seasoning
  • 1 (8-ounce) package cream cheese

Top it off

  • 1/2 cup freshly grated Parmesan cheese
  • Fresh basil pesto optional

Instructions 

  • Preheat oven to 350ยฐF. Generously grease a 9x13-inch casserole dish with cooking spray and set aside. Bring a large pot of water to boil.
  • Trim the snap peas, peel and coin the carrot, and halve the cherry tomatoes. Thinly slice the mushrooms, peppers, and summer squash.
  • When the water boils, add 2 teaspoons salt. Prepare tortellini according to package directions. In the last two minutes of boiling the tortellini, add in sugar snap peas and carrots. Drain everything, then transfer to the prepared casserole dish.
  • Meanwhile, over medium-high heat, sautรฉ mushrooms, peppers, and summer squash in the olive oil until crisp-tender, about 5 minutes. Pour over the tortellini, peas, and carrots in the casserole dish. Add halved tomatoes and frozen corn and gently toss everything to combine.
  • In a small pot, melt the butter over medium-heat. Once butter is melted, whisk in flour to create a paste and cook 1 minute. Gradually and slowly add in stock and whisk until completely smooth. Gradually, while stirring constantly, add in milk and whisk until smooth and thickened. Add garlic powder, salt, pepper, dried basil, and Italian seasoning. Stir. Meanwhile, soften the cream cheese (out of its package) in the microwave. Once soft, add into cream sauce and whisk briskly until completely smooth and melted. Taste the sauce and adjust seasonings, adding more salt/pepper if needed.
  • Pour the sauce over the veggies and tortellini. Stir gently in the casserole dish, then press into an even layer. Add Parmesan cheese on top. Bake 20โ€“25 minutes or until warmed through and cheese is melted on top. Broil for the last 1โ€“2 minutes if desired. Enjoy hot! I enjoy this with a big scoop of pesto if there is some lingering in the fridgeโ€”so good, but totally optional.

Recipe Notes

Storage: This dish is best enjoyed the same day itโ€™s made. Leftovers reheat okay, but sometimes get a bit watery. This dish does not freeze and thaw well because of all the veggies and the dairy. Feel free to halve the recipe!
Make ahead: Prepare this casserole as directed but donโ€™t bake it. Instead, cover and chill up to 24 hours. Bake, covered, in a 350ยฐF oven about 45โ€“55 minutes or until hot.

    Thank you Marla! ๐Ÿ™‚

  2. Laura says:

    Could you prep ahead (say in the morning), then refrigerate, and bake for dinner?

    1. chelseamessyapron says:

      Absolutely! ๐Ÿ™‚

  3. Emily says:

    This looks fantastic and is now in my oven! Can’t wait to taste it! Any tips on turning this into a crockpot meal? Turning on my oven on this hot day was the only downfall.

    1. chelseamessyapron says:

      So glad you tried this! I hope you love it ๐Ÿ™‚ I’m sorry, I don’t have any tips for changing it over to the crockpot as I haven’t experimented with this recipe in the crockpot. With all the veggies and the tortellini I’m not sure it would be a very good crockpot meal…the oven really makes the veggies crispy which a crockpot can’t do.

    The perfect way to use the bounty of veggies coming out of our garden right now! I’m a tortellini lover, too.

    I made this exactly according to the recipe and it came out FANTASTIC! The creamy sauce was tasty and not too heavy. A perfect filling dish with summer veggies. You made this vegetarian (and her meat-eating hubby) very happy. Oh, I did roast the halved tomatoes first, that’s the only change I made. Which I recommend. ๐Ÿ™‚

    1. chelseamessyapron says:

      Oh that is SO great to hear! Thanks so much for the comment Katie ๐Ÿ™‚ And I LOVE the idea of roasting the tomatoes first, I’ll definitely have to try that!

    2. Kat says:

      How did you roast the tomatoes thanks

    Do you think this meal would freeze well? I usually stay away from sauces with dairy in them as far as freezing meals, didn’t know if you had tried it though.

    1. chelseamessyapron says:

      I’m sorry, I haven’t tried freezing this dish. I don’t think it would do particularly well being frozen, but I can’t say for sure.

  7. Nicole says:

    I don’t know what it is about tortellini, but I just adore it. Maybe for it’s cuteness? Maybe for the tiny title jewel in the center?? Whatever the reason, I love them, and I love this!

  9. Medha says:

    I loooove stuffed pastas, especially tortellini! This look indulgent and satisfying, yet at the same time, packed with vegetable goodness ๐Ÿ™‚

  10. Sam says:

    Chelsea this looks so good! I love how perfect this is for summertime, I will definitely have to make this sometime soon (and I love how easily adjustable it is for personal preference!)! ๐Ÿ™‚
