Ingredients

• 4 cups yellow squash, sliced thin
• 1 pound Italian sausage, casings removed
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 cup shredded mozzarella cheese
• 1 cup shredded cheddar cheese
• 1 half cup sour cream
• 1 half cup mayonnaise
• 2 large eggs
• 1 cup crushed buttery crackers
• 2 tablespoons melted butter
• Salt and black pepper to taste

Step By Step Instructions

1. Preheat your oven to 375 degrees F. Lightly grease a 9×13 baking dish.
2. In a large skillet over medium heat, cook the Italian sausage. Break it into small pieces as it browns. Cook until no pink remains, then remove and set aside.
3. In the same skillet, add the sliced squash and diced onion. Cook for 8 to 10 minutes until the squash is tender and most of the moisture has cooked off. Add garlic and cook for 1 more minute.
4. In a large bowl, whisk together the eggs, sour cream, and mayonnaise. Stir in mozzarella and cheddar cheese. Add salt and pepper to taste.
5. Add the cooked sausage and squash mixture into the bowl. Stir gently until everything is well combined.
6. Pour the mixture into the prepared baking dish. Spread it out evenly.
7. In a small bowl, mix the crushed crackers with melted butter. Sprinkle this mixture evenly over the top.
8. Bake for 30 to 35 minutes, until the top is golden and the center is set. Let it rest for 10 minutes before serving.

Common Mistakes To Avoid

• Not cooking out the squash moisture. Squash holds a lot of water. If you skip this step, the casserole may turn watery.
• Overbaking. Bake just until the center is set. Overbaking can make it dry.
• Skipping seasoning. Italian sausage adds flavor, but always taste and adjust salt and pepper.

Tips For Success

• Use mild or spicy Italian sausage based on your taste. Both work well.
• If you want a lighter version, you can use Greek yogurt instead of sour cream. This makes it fit nicely into healthy casserole recipes.
• Slice the squash evenly so it cooks at the same speed.
• Let the casserole rest before slicing. This helps it hold its shape.

How To Serve

This dish is filling on its own, but you can serve it with a fresh green salad or simple garlic bread. It pairs well with other baked casserole recipes if you are making a big family meal. For a holiday table, it works beautifully as a Mother’s day recipe since it feels comforting and homemade.
