Creamy Baked Pasta is the Ultimate Comfort Food

Baked pasta is just so comforting! I’m a big fan of baked spaghetti, macaroni, ziti, and of course lasagna.

This delicious bake is so easy to prepare, and serves a whopping 8 people with just some pasta, sauce, cheese, and veggies! It’s economical, easy, and utterly fantastic.

Fresh veggies are gently sautéed with garlic and olive oil, and then blended with a whole jar of red sauce (I like marinara), tender penne pasta, cream cheese, and mozzarella. It’s gooey, tangy, savory goodness in a 9×13 pan! Definitely a crowd-pleaser, and definitely easy on the cook. Win-win!

Recipe Ingredients

  • Penne Pasta: You’ll need 3 cups, or 8 oz (½ lb).
  • Olive Oil: For sauteing the veggies, so choose a light or medium olive oil
    Yellow Onion: Dice one small yellow onion.
  • Garlic: Mince or put through a garlic press.
  • Zucchini: Cut up one zucchini into thin half-moons.
  • Mushrooms: I like to use Baby Bella or button mushrooms. Either way, wash and slice.
  • Salt and Pepper
  • Cream Cheese: About 8 oz, cubed.
  • Sour Cream: One 8 oz package.
  • Shredded Mozzarella: I like to shred my own fresh mozzarella, but you can also use pre-shredded.
  • Italian Seasoning and Dried Basil
  • Salt and Pepper
  • Chopped Fresh Parsley: For garnish.

How to Make this Creamy Baked Pasta

  1. Prepare the Pasta and Sauté the Veggies: Cook the pasta in boiling water according to the package directions. In the meantime, heat the oil in a 12-inch skillet and saute the veggies, starting with the onions and then adding garlic, zucchini, and mushrooms.
  2. Combine All Ingredients: When the pasta is done cooking, drain it well and return it to the pot. Add the sauteed veggies, cream cheese, sour cream, pasta sauce, seasonings, and half the mozzarella. Stir well to combine. Taste for salt and pepper.
  3. Bake: Pour the mixture into a greased 9×13 baking dish or pan. Top with the remaining mozzarella, and bake at 375˚F for 20 minutes or until the cheese is bubbly and golden brown. Let stand 10 minutes before serving.
  4. Serve and Enjoy!

Tips for the Best Baked Pasta

  • Watch the Time: If you’re concerned about soft pasta, and would prefer a more al dente finished product, you can undercook the pasta in the boiling water. Simply shave off a minute or two of the cook time recommended on the package. Then, after the pasta has baked in the sauce, it will be al dente.
  • Use the Broiler: If you’re having trouble getting a really golden top to your bake, try turning on your oven’s broiler at the end of the baking time. Broiling is a great way to brown any baked item – but be careful! The intense heat can take your food from perfect to burned very quickly.
  • Add Protein: This dish is quite flexible– if you’d like to make it a meaty entree, try adding ½ lb of browned ground beef, or some grilled chicken pieces, before baking. Yum!

What Goes with Baked Pasta?

  • If you need to put dinner on the table fast, this recipe works perfectly with some simple breadsticks and a prepared salad. Dinner? Done! I have an entire collection of salad recipes to choose from too.
  • Have a little more time? Then do serve with bread– but make it a warm and homey Spinach and Feta No-Yeast Bread.
  • Finish this dish with a simple sampler of fresh fruit – think grapes, melon chunks, and maybe some pineapple. So good, and good for you!

How to Store and Reheat Leftovers

  • Leftovers can be stored in the refrigerator, tightly covered, for 3 to 5 days.
  • If you would like to freeze this dish, first cool it completely. Then place individual portions in plastic freezer bags, pushing out as much air as possible before sealing, and freeze for up to 2 months.
  • To reheat, first thaw the portions (if frozen). Then place in the oven, covered with foil to trap steam. Bake at 350˚F for 15-20 minutes, or until heated through.
