Ingredients

Here’s what you’ll need for this delectable Yellow Squash Casserole:

• 1/4 cup mayonnaise
• 1/3 cup sour cream
• 1/4 cup milk
• 1 cup heaping shredded cheddar cheese
• 24 Ritz crackers
• 2 tablespoons butter, melted

Ingredient Notes and Easy Substitutions

• Yellow Squash: If you can’t find yellow squash, zucchini or a mix of both can work just as well.
• Onion: For a milder flavor, consider using sweet onions or shallots.
• Cheese: Feel free to experiment with different cheese varieties, such as pepper jack or mozzarella, for added flavor.
• Crackers: Only Ritz crackers? Try using crushed breadcrumbs or panko for a gluten-free option.

Instructions

1. Preheat your oven to 350 degrees Fahrenheit and lightly grease a casserole dish.
2. Steam the squash and onion until just tender, about 5 to 7 minutes. This ensures they won’t release too much moisture during baking.
3. Season the steamed squash and onion with salt and pepper to taste.
4. In a large bowl, whisk together the egg, mayonnaise, sour cream, and milk until smooth.
5. Stir in the cheese, followed by the cooked squash and onion, mixing until everything is well combined.
6. Transfer the mixture to the prepared casserole dish.
7. Crush the Ritz crackers and scatter them evenly over the top of the squash mixture.
8. Drizzle with melted butter to add an irresistible flavor.
9. Bake for 30 minutes, until the top is golden and the casserole is heated through.

Expert Tips for the Best Results

• Prep Ahead: You can steam the squash and onion earlier in the day and store them in the refrigerator until you’re ready to assemble the casserole.
• Ensure Creaminess: Make sure you don’t overcook the squash; it should be tender but still have some structure to maintain that classic casserole texture.
• Visual Cues: Look for a golden-brown crust when removing from the oven for the best flavor and texture.

Variations

1. Add Protein: Include cooked diced chicken or turkey to make this dish more filling.
2. Herb Infusion: Fresh herbs like thyme or basil can elevate the flavor profile beautifully.
3. Spicy Kick: Add diced jalapeños or crushed red pepper flakes for a spicy version.
4. Veggie Additions: Mix in other vegetables such as bell peppers or mushrooms for added nutrition and flavor.
5. Bacon Lovers: Crispy crumbled bacon can be added for a savory touch that complements the creamy filling.

• Grilled chicken or baked fish for a balanced meal.

• Cornbread or crusty bread to soak up the creamy goodness.
• For a drink, consider sweet tea or a light white wine to complement the flavors.

Storage and Reheating

Common Mistakes to Avoid

• Overcooking: Be careful not to overcook the squash during steaming; you want it tender but not mushy.
