The Origins of a Comfort Classic

Southern squash casserole is a product of farm-to-table living, where families relied on the bounty of summer gardens. Yellow squash, a fast-growing and abundant vegetable, found its way into many homes—baked, sautéed, fried, or layered in casseroles like this one. Over time, cooks began adding ingredients like cheddar cheese, eggs, and crushed crackers to give the dish structure and indulgence.

Today’s version has evolved into a beloved comfort food staple, pairing beautifully with ham, roast chicken, or collard greens.

Ingredient Spotlight: The Essentials of Cozy

Here’s what you’ll need for this classic cheesy squash casserole:

• Yellow squash – fresh, tender, and mildly sweet
• Cheddar cheese – sharp and melty for that cheesy finish
• Onion – adds a savory base note
• Butter – richness and flavor
• Eggs – help bind the mixture
• Sour cream or milk – adds creaminess
• Crushed buttery crackers (like Ritz) – crispy golden topping
• Seasonings – salt, pepper, paprika, garlic, and onion powder

How to Make Southern Squash Casserole (Step-by-Step)

Here’s a foolproof breakdown to get the best results:

1. Preheat your oven to 350°F (175°C).
2. Slice the yellow squash into thin rounds.
3. Sauté squash and onions in butter until just tender. This step prevents the dish from becoming too watery.
4. In a large bowl, mix cooked squash, eggs, shredded cheddar, sour cream (or milk), and seasonings.
5. Transfer mixture to a greased casserole dish.
6. Top with crushed buttery crackers and a sprinkle of extra cheese.
7. Bake uncovered for 30–35 minutes, or until golden and bubbling.

Tip: Don’t skip sautéing the squash. Raw squash contains a lot of moisture and can make your casserole soggy.

To take your casserole from good to spectacular, follow these tips:

• Drain or press squash after cooking to remove excess liquid.
• Use a mix of sharp cheddar and Monterey Jack for a balanced cheese pull.
• Layer cheese in the middle and on top for extra gooeyness.
• Add a pinch of nutmeg to enhance the creaminess subtly.
