Ingredients You’ll Need
- 2 medium yellow squashes, sliced
- 1 cup shredded Cheddar cheese
- 1 cup crushed buttery crackers
- 1/2 cup milk
- 1/4 cup onion, chopped
- 2 eggs, beaten
- Salt and pepper to taste
- Butter for greasing the dish
Chef notes:
- Fresh onion = brighter bite
- Use sharp Cheddar for more flavor
- Buttered crackers give a crisp top
How to Make It
- First, preheat your oven to 350°F (175°C) and butter a 9×9-inch casserole dish so the edges brown nicely.
- Next, toss the sliced squashes and chopped onion in a large bowl; the squash will look glossy when it has enough milk. Meanwhile, I like to let the slices sit 5 minutes so they soften slightly. Also useful: check more comforting recipes at my casserole roundup.
- Then stir in the beaten eggs, milk, salt, and pepper. Mix briskly until the mixture looks cohesive and slightly custardy.
- Now fold in the shredded Cheddar; it should cling to the squash and make the mixture feel sticky and rich.
- Pour the squash mix into the prepared dish, smoothing the top with a spatula. Sprinkle the crushed buttery crackers evenly over the surface for a crunchy finish.
- Bake for 30–35 minutes. You’ll know it’s done when the center sets, the edges bubble, and the top turns a warm golden brown. Finally, let it cool 5–10 minutes so the casserole firms up before serving.
Tip: when the crackers toast, you’ll catch a nutty, buttery smell—that’s your cue it’s time to pull the pan.
Kitchen Tips (From My Kitchen)
- Time-saver: Slice squashes thinly with a mandoline to speed prep and ensure even cooking.
- Common mistake + fix: If the casserole is watery, bake a few extra minutes uncovered; the liquid will reduce and the center will set.
- Simple variation: Stir in a handful of cooked bacon or chopped chives for extra savoriness.
Serving Ideas
- Weeknight dinner: Serve with roasted chicken and a crisp green salad; garnish with chopped parsley.
- Brunch: Pair with poached eggs and toast for a savory morning spread.
- Holiday table: Offer as a mellow, crowd-pleasing side next to ham and mashed potatoes.
- Potluck: Bring it warm in the dish; include a small serving spoon and buttered crackers on the side.
I often top slices with a little extra shredded Cheddar or a sprinkle of smoked paprika for color.
Also, if you’re building a menu, consider pairing this with other easy casseroles from my comfort food casserole list.
Storing & Leftovers
- Fridge: Store in an airtight container for 3–4 days.
- Freezer: Freeze cooled portions up to 2 months; thaw overnight in the fridge.
- Reheat: Warm in a 350°F oven for 10–15 minutes to keep the cracker topping crisp.
Leftover idea: Turn slices into a hearty sandwich with sliced turkey and mustard.
