How to Make Squash Casserole with Salsa
This casserole is super easy to make. Start with slicing some yellow squash. Combine squash, cheese, onion, green chiles and jalapeños. Sprinkle with flour, cumin and salt. Toss together and spread into a baking dish. Top with salsa and more cheese. Pop the casserole in the oven and bake. Garnish the casserole with chopped red and green onions.
- I used yellow squash in this dish. This would also be great with half squash, half zucchini.
- Can I make squash casserole in advance? Sure! You can assemble the casserole ahead of time and refrigerate until ready to bake.
- My favorite store-bought salsas are Mateo’s and Kylito’s Salsa. I buy both at Walmart.
- Can use homemade salsa. Here is our favorite recipe: https://www.plainchicken.com/superior-grill-salsa/
- I used cheddar cheese. This is also delicious with a Mexican cheese blend or pepper jack cheese.
- Is Southwestern Squash Casserole spicy? This casserole does have a little kick from the jalapeños, and salsa. You can substitute green chiles for the jalapeños and mild salsa if you are worried about the heat.

Do you need to cook the squash first?
Do you think I could use cooked spaghetti squash instead of regular yellow squash?
I have not made this recipe with spaghetti squash, so I can't say with certainty how it would taste. You can certainly give it a try!
IT was delicious. I made it using another commenters suggestion of adding taco meat. Since our squash we pick is fairly small I was unsure of the quantity, so I just saw how much would fill my dish. I think next time I will sauté onions and garlic and our jalapeño peppers.
Do you think I could prepare all of the ingredients in a tin and freeze to bake later?
Absolutely
