  3. Baked Rotini Casserole Recipe

A pasta bake may be hands-down the most comforting casserole one can make. I will claim that a casserole can be anything that is layered in a baking dish and turned into an entire meal all in one. This baked rotini casserole gives whispers of lasagna without too much effort. Full of flavor, the best part is the time can be cut down by using your favorite jarred red sauce.

While many of my recipes include meat, this is one where meat is optional. The casserole can easily be vegetarian by eliminating the sausage. A casserole is meant to be easy to make and easy to customize for each family or individual.

The ingredients for this baked rotini casserole

  • Rotini pasta has so many swirled edges that really hold onto the sauce. This way, each piece of pasta is packed full of flavor. Make sure to cook the pasta to al dente, which means slightly underdone, so the pasta really absorbs the sauce.
  • Italian sausage has the ideal mixture of a sweet, spice, and herbs. You can opt for a sweeter or spicier variety to fit your liking.
  • Marinara sauce is the major flavor in this casserole. I often use home preserved sauce, but any store-bought version will work perfectly.
  • Whole milk ricotta adds a creamy richness to the casserole. Trust me: a layer of the riccota may become your favorite part. For the most flavor, choose whole milk ricotta if possible.
  • Eggs are oftentimes what binds ingredients together. And in this recipe, one egg added to the ricotta layer is just enough to help it all hold together.
  • Dried basil and dried oregano are often in the pantry, but tend to be forgotten. The fact of the matter is that they have so much flavor! There’s no need to buy fresh, especially at this time of the year.
  • Parmesan cheese with it’s salty, iconic flavor acts almost like a seasoning. And it’s very welcome!
  • Mozzarella cheese is the finishing touch. Mozzarella easily melts over the casserole and is best when it just begins to brown. Browning means that there’s even more flavor!

If you’re looking to save even more time, make this casserole the day before serving so it’s ready to pop in the oven. Remember: storing the unbaked casserole in the refrigerator will require a longer baking time since it will be colder than when freshly made.

Casseroles are a staple because they offer an entire meal without all of the separate dishes. The leftovers are great for taking to work, school, or simply eating for the next few evenings.

    I tell all my friends and family how talented you are. You can cook, garden, educate us how to clean copper pots, how to decorate a table, how to decorate a tree, etc, etc, etc. You truly are a jack of all trades. Love watching your videos.

    What is the difference between marinara sauce and spaghetti sauce? Also would you serve a side of vegetables or salad with a dish like this?

    1. Spaghetti sauce is a broad term for any kind of red (tomato) sauce. You could make Bolognese which is a red sauce with meat, you could make marinara which is a red sauce without meat, vodka, pink sauce, one heavy on the veggies is a garden style.

  3. This was so easy and fun to make. I substituted a lot, like whatever pasta I had in the cupboard instead of rotini, ground sausage instead of links, and then I added some kale (since I already had this too) for a bit of green in the middle layer. I’ll be making this when I’m craving lasagna instead! Time saver.

  4. I really love your Videos, you seem like you would be a really great friend! And a lot of fun to just hang out with and chat.

    Made your Baked Rotini Casserole last night and we loved it. Although it is a very simple recipe to make it does take a little more time for a week night dinner, with precooking the noodles and sausage and then baking. But positively worth a easy Sunday dinner.

    Kaleb, I love all pastas and pasta dishes/casseroles . This looks like a “must” make.
    I like all of your homey comfort food. We all need a little warm comfort food this time of the year.
    How about Tapioca? That’s definitely a homey comfort dessert. Just a thought. Keep up the good work, you make a lot of people happy. CW

    Mine is in the oven now, but I wanted to confirm something, do you really only use 8oz of ricotta? I had a 15 oz container and used about 2/3 and it seemed like barely enough. Will wait and see how it comes out. Now I have to figure out what to do with a few ounces of ricotta 🙂

  8. Love love your Facebook page. Your recipes are bursting with flavor and your personality is a joy to watch. Feel like I’m your neighbor next door watching you cook. Thank you for all the tips on various subjects. God bless.
