A Texan Memory with Squash Casserole
Every family has that one dish that immediately transports them back to the heart of their home. For me, it’s the memory of a cozy evening gathered around the table in San Antonio, the kitchen alive with laughter and the irresistible aroma of dinner. That night, the star wasn’t a fancy main course—it was a bubbling, golden San Antonio squash casserole resting proudly in the center of the table.
The warmth of the casserole filled the room. The sweet scent of sautéed squash mingled with richly caramelized onions, roasted peppers, and just the right hint of spice. When my mother set the steaming dish down, topped with a crusty, cheesy layer, we all leaned in, eager to dig into a recipe that felt both timeless and new.
It was one of those meals where no one left the table hungry. Each serving melted into creamy comfort while still carrying the freshness of garden-picked squash. Paired with roasted chicken and a simple salad, this casserole proved that even side dishes can steal the spotlight.

Ingredients
Instructions
1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
2. Heat oil in a large skillet over medium. Sauté squash, onion, bell pepper, and jalapeño with a pinch of salt until just tender, 7–9 minutes; drain off excess liquid.
3. In a small saucepan or bowl, whisk sour cream with garlic powder, paprika, black pepper, and remaining salt until smooth and warmed.
4. In a mixing bowl, combine sautéed vegetables, creamy mixture, roasted corn (if using), 3/4 cup cheddar, and pepper jack (if using).
5. Spread mixture in the baking dish. Top with remaining cheddar, then sprinkle breadcrumbs evenly; mist with oil or dot with butter.
6. Bake 25–30 minutes until bubbling at the edges and the top is golden brown.
7. Rest 5–10 minutes before serving so the casserole sets for cleaner scoops.
8. Make-ahead: Assemble through topping, cover, and refrigerate up to 24 hours; bake 30–35 minutes from chilled. Store leftovers 3–4 days or freeze up to 2 months.

Casseroles are often admired for their practicality, and this one was no exception. It checked every box: portable for potlucks, easy to prepare, reheats beautifully, and pleases both kids and adults. Among easy side casserole recipes, this San Antonio version stood out because of its personality—the way it blended Southern comfort with bold Texas character.
Why This Dish Stands Out
Traditional Southern kitchens have long treasured squash casseroles as part of Sunday dinners, church potlucks, or holiday spreads. Typically made with fresh yellow squash, onions, cream, and a modest sprinkling of breadcrumbs, it’s the epitome of farmhouse simplicity. But in San Antonio, where Tex-Mex flavors thrive, that classic recipe transforms into something unforgettable.
Here, the humble squash gets elevated with accents of green peppers, zesty onions, and melted cheese that stretches with every spoonful. Adding jalapeños or a touch of roasted corn layers in a subtle Southwestern kick without overpowering the vegetable’s natural sweetness. It’s comfort food that doesn’t weigh you down—where the indulgence of cheesy, baked casserole meets the lightness of farm-fresh produce.
That’s the beauty of this dish: it strikes a perfect balance. The cream and cheese bring satisfying richness, while the yellow squash keeps it bright and fresh. At its best, the San Antonio squash casserole bridges tradition and creativity, reminding us that family favorites can always evolve without losing their roots.
