Friends Helping Friends
Last month I was sick for over two weeks, and didn’t have the energy to do much of anything. I cut back my work schedule, but even so, work combined with keeping my children from hurting each other and destroying the house, it was all I could do to stay awake until 8PM. Fortunately, I have an amazing husband, and we have an amazing group of friends, so I had a lot of help.
A few people made us dinner, which was HUGE. I’ve written myself a giant mental note to consider making people meals more often, because those meals made life a lot more manageable those nights. A friend from work made us a delicious pasta bake. I liked it so much that I wanted to recreate something similar.

I didn’t want to ask my friend for her recipe, since I wanted to add my own spin and make sure it was truly my own.I started with rigatoni noodles that I mixed with my homemade marinara sauce. Side note about making your own marinara sauce: It has multiple benefits. It’s cheap, it’s easy, you know everything going into your sauce, and it’s delicious.
After the marinara sauce was made, I added some Italian chicken sausage, sauteed spinach, and onion. Finally, I topped it with plenty of cheese before baking it off. It turned out perfectly for my family!

Italian Sausage Pasta Bake
This recipe is easy, and quick, but after a few experimentations with it, I have some notes for you:
- You can use any noodle you want. I prefer rigatoni as I like the way it makes the casserole less dense than it is with smaller noodles.
- I have made this with Sweet Apple Chicken Sausage, which was good, but I much prefer the Italian Chicken Sausage. Ground beef or another cooked meat would also work.
- If you’re going to freeze this meal, I recommend that you prepare it up to the point of baking, then cover it with plastic wrap and aluminum foil before freezing it. I also recommended thawing it before baking it.
- Depending on the type of canned tomatoes you use, the salt needed may vary. Be sure to taste your sauce and adjust as necessary.
- You can add other vegetables or herbs to truly make this casserole your own. Experiment, have fun!
