yellow squash, sliced

directions
I preheat the oven to 350°F.
In a large skillet, I melt 3 tablespoons of butter over medium heat and sauté the squash and onion for about 10–12 minutes, until they’re soft and lightly golden. I let the mixture cool slightly.
In a mixing bowl, I combine the sour cream, cream of chicken soup, beaten eggs, shredded cheddar cheese, garlic powder, paprika, salt, and pepper.
I stir in the squash and onion until everything is well mixed.
I spoon the mixture into a greased 9×13-inch baking dish.
In a small bowl, I combine the crushed Ritz crackers with melted butter, then sprinkle the mixture evenly over the top.
I bake the casserole for 30–35 minutes, until the top is golden and bubbly. I let it rest for 5 minutes before serving.
Servings and timing
This recipe makes about 8 servings. It takes approximately 15 minutes to prep and 30–35 minutes to bake, plus 5 minutes of resting time before serving.
Variations
I sometimes swap out the cream of chicken soup for cream of mushroom or cream of celery for a different flavor profile.
For a vegetarian version, I use a plant-based cream soup and skip the eggs.
Using pepper jack or Monterey Jack cheese instead of cheddar adds a little kick.
A sprinkle of fresh herbs like thyme or parsley on top adds brightness.
storage/reheating
I store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, I warm it in a 350°F oven for about 15–20 minutes, or until heated through. For a quicker option, I microwave individual portions for 1–2 minutes.
FAQs
How do I keep the casserole from getting watery?
I make sure to sauté the squash thoroughly to release as much moisture as possible before mixing it into the casserole. Letting it cool slightly also helps reduce excess water.
Can I freeze squash casserole?
Yes, I freeze it after baking. Once it cools completely, I cover it tightly with foil and freeze for up to 2 months. I reheat from frozen at 350°F for about 40–45 minutes.
Can I make it ahead of time?
Absolutely. I prepare the casserole, cover it, and refrigerate it for up to 24 hours before baking. I add the cracker topping right before it goes into the oven.
What can I use instead of Ritz crackers?
I sometimes use crushed cornflakes, panko breadcrumbs, or even plain potato chips for a different crunch.
Is this recipe gluten-free?
As written, it’s not gluten-free because of the Ritz crackers and the canned soup. I use gluten-free crackers and a certified gluten-free soup to adapt it.
