Why You’ll Love this Smoked Sausage and Noodle Casserole
- Easy. This recipe takes advantage of my favorite dump-and-bake method to eliminate tedious prep work. There’s no need to boil the pasta in advance or to pre-cook the sausage or veggies. Instead, all of the ingredients mingle, share seasonings, and simmer together in one dish in the oven.
- Family-friendly. There are certain recipes that are just guaranteed to be a hit with the kids (and with the husband)! If it involves creamy noodles, I can throw just about anything else into the casserole and know that my boys will clean their plates.
- Versatile. The casserole is easily adaptable, so you can change up the ingredients to suit your family’s preferences or to use up whatever you have on hand. For instance, omit the peas, but add frozen corn, frozen diced carrots, fresh or thawed broccoli florets, or sliced fresh mushrooms. You can use andouille sausage (if you like it spicy), fully-cooked Italian sausage, or even hot dogs. If you don’t like cream of celery soup, swap it out for cream of mushroom or an extra can of cream of chicken soup instead. The options are endless!

Do you have to cook pasta before putting it in a casserole?
While most casserole recipes call for cooking the pasta before mixing it into the dish, this particular recipe is designed specifically for uncooked pasta. That means that you do not boil the noodles in a saucepan on the stovetop before adding them to the casserole dish.
Instead, the pasta cooks right in the oven with the rest of the ingredients. This requires extra liquid in the pan (since the pasta absorbs a lot of liquid as it cooks), and extra cooking time to make sure that the noodles are tender.

Ingredients
This is just a quick overview of the ingredients that you’ll need for a creamy sausage noodle tomato casserole. As always, specific measurements and step-by-step instructions are included in the printable recipe box at the bottom of the post.
- Condensed cream of celery soup and condensed cream of chicken soup: or use any combination of two condensed soup flavors that you prefer. I like the reduced-sodium or Healthy Request varieties in this recipe, since the sausage can be salty on its own.
- Milk and chicken broth or water: to thin the creamy sauce.
- Dried parsley, dried oregano, dried thyme, garlic powder, and onion powder: add earthy, savory flavor to the sauce.
- Kosher salt and ground black pepper: to enhance the flavors of the other ingredients in the dish.
- Crushed red pepper flakes: these are optional, but add a nice hint of spicy kick in the background.
- Smoked sausage: or sub with kielbasa, hot dogs, fully-cooked Italian sausage, or just about any other fully-cooked sausage that you enjoy.
- Canned petite-diced tomatoes: or use a can of regular diced tomatoes if that’s what’s available. Make sure that you grab the big 28-ounce can!
- Penne pasta: just the uncooked pasta — no need to boil it first.
- Fried onions: I like French’s brand crispy fried onions, but any similar variety will work.
- Cheese: Colby Jack cheese or cheddar cheese both work well here, but mozzarella cheese, Pepper Jack cheese, or another type of cheese is also great.
- Peas: stir the frozen peas into the pan at the very end, since they will heat through almost immediately.

Preparation and Storage Tips
- Make Ahead: You can assemble the pasta dish a few hours in advance, or even leave it covered in the refrigerator overnight before baking. The pasta will start to soften and absorb some of the liquid as it sits, so you may need to decrease the baking time slightly. You don’t want to overcook the casserole or you’ll end up with gummy, mushy pasta.
- Storage: This casserole is best enjoyed immediately from the oven. Leftovers will keep in an airtight container in the refrigerator for 3-4 days. The pasta will dry out a bit as it sits.
- I do not recommend freezing this casserole because pasta has a tendency to get gummy and mushy when thawed.

Recipe Variations
- Any variety of smoked sausage is fine (such as turkey sausage or beef sausage), or sub with a different type of fully-cooked sausage. Other good options include andouille sausage, kielbasa, hotdogs, fully-cooked Italian sausage, or spicy smoked sausage.
- Don’t have penne pasta? Substitute with other similar short pasta shapes such as rotini, rigatoni, or elbows. Just pick a pasta that has a similar cooking time as the penne (about 11-12 minutes recommended on the package directions) — otherwise you’ll need to adjust the casserole’s baking time in the oven.
- Use any variety of condensed soup that you like. For instance, substitute with organic condensed soup, homemade condensed soup, or with other flavors of condensed soup (such as a can of Cream of Mushroom soup).
- Try different vegetables. For instance, instead of frozen peas use frozen corn. You can also stir in some sliced fresh mushrooms, diced green pepper, sliced or grated zucchini, or broccoli florets at the beginning of the baking time.
- If you’re cooking for a smaller family, cut all of the ingredients in half and bake the casserole in an 8-inch square pan (or a 2-quart casserole dish). The rest of the instructions remain the same.

Tips for the Best Smoked Sausage Pasta Casserole Recipe
- Total cooking time will vary depending on the type of pan that you use and on your individual oven. A glass or ceramic casserole dish will take longer than a metal pan, for instance. To know when your casserole is done, taste a bite of the pasta. The noodles should be tender and the sauce should be thick.
- Be careful not to overbake the casserole or the pasta will become mushy.
- Garnish the finished dish with fresh herbs (such as fresh parsley, fresh basil, or fresh thyme) for even more flavor.
- For a richer, creamier sauce, stir in ½ cup of room-temperature sour cream towards the end (at the same time that you stir in the peas).
- Make sure that you use the big 28-ounce can of diced tomatoes (not the smaller 14.5 ounce can).
