What Is Summer Squash?
Summer squash refers to several varieties of tender-skinned squash harvested during warm weather months. Yellow squash is most commonly used in casseroles because of its mild flavor and soft texture when cooked.
Popular summer squash varieties include:
- Yellow crookneck squash
- Straightneck yellow squash
- Zucchini
- Pattypan squash
This casserole traditionally uses yellow squash, but zucchini can easily be substituted or combined for extra color and flavor.
Ingredients
- 6 cups yellow summer squash, sliced
- 1 medium onion, diced
- 2 cups shredded sharp cheddar cheese
- 1 cup sour cream
- 1 sleeve Ritz crackers, crushed
- 2 large eggs
- 4 tablespoons unsalted butter, melted
- 2 tablespoons butter for sautéing
- 2 cloves garlic, minced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon paprika
- 1 tablespoon chopped parsley for garnish
Why Ritz Crackers Work So Well
The buttery flavor of Ritz crackers gives this casserole its signature taste and texture. Unlike breadcrumbs, Ritz crackers soften slightly while still maintaining a crisp golden topping during baking.
The crackers also absorb moisture from the squash mixture, helping create a rich and cohesive casserole instead of a watery vegetable bake.
For even more flavor, some cooks mix extra melted butter into the cracker topping before baking.
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish with butter or nonstick spray.
- Wash and slice the yellow squash into thin rounds. Dice the onion and mince the garlic.
- Bring a large pot of salted water to a boil. Add the sliced squash and cook for about 5 minutes until slightly tender. Drain thoroughly and set aside.
- In a large skillet, melt 2 tablespoons of butter over medium heat. Add onions and sauté for 4–5 minutes until softened. Stir in the garlic and cook for 1 additional minute.
- Transfer the cooked squash to a large mixing bowl. Add sautéed onions and garlic.
- Stir in sour cream, shredded cheddar cheese, eggs, salt, black pepper, and paprika. Mix until fully combined.
- Fold in half of the crushed Ritz crackers to help bind the casserole mixture.
- Pour the squash mixture into the prepared baking dish and spread evenly.
- In a separate bowl, combine the remaining crushed Ritz crackers with 4 tablespoons melted butter.
- Sprinkle the buttery cracker topping evenly across the casserole.
- Bake uncovered for 30–35 minutes until hot and bubbly with a golden brown topping.
- Remove from the oven and allow the casserole to rest for 5 minutes before serving.
- Garnish with chopped parsley and serve warm.
Tips for the Best Squash Casserole
Drain the Squash Well
One of the biggest mistakes when making squash casserole is leaving too much moisture in the cooked squash. Summer squash naturally contains a lot of water, so proper draining is essential.
After boiling the squash, let it sit in a colander for several minutes. You can even gently press the squash with paper towels to remove excess moisture.
Use Sharp Cheddar Cheese
Sharp cheddar gives the casserole a deeper, richer flavor than mild cheese. Freshly shredded cheese also melts more smoothly than pre-packaged shredded cheese.
Don’t Overcook the Squash
The squash should be tender but not mushy before baking. Since it continues cooking in the oven, avoid boiling it too long.
Add Extra Crunch
For an even crispier topping, add extra crushed crackers during the final 10 minutes of baking.
Delicious Variations
One of the best things about this squash casserole with Ritz crackers is how customizable it can be.
Add Bacon
Crispy cooked bacon adds smoky flavor and extra richness.
Try Different Cheeses
Swap cheddar for Monterey Jack, mozzarella, Gruyère, or Parmesan for unique flavor combinations.
Make It Spicy
Add diced jalapeños, cayenne pepper, or crushed red pepper flakes for a spicy kick.
Include Zucchini
Use half zucchini and half yellow squash for a colorful variation.
Add Fresh Herbs
Fresh thyme, basil, or chives bring brightness and fresh garden flavor.
