Are you feeling squashed from the weight of all the fresh Summer Squash and Zucchini that’s collecting on your kitchen counters? I didn’t plant this year, but others most certainly have and are being very generous in gifting their bounty to me.
One of the first zucchini recipes I make each and every year is this luscious baked zucchini squash casserole recipe. It’s truly one of most favorite Summer vegetable casseroles.
And its a gluten free zucchini casserole. The binding comes in the form of corn meal rather than bread crumbs.
With eggs, cheese and milk, the end result is more like a fluffy custard or a summer squash souffle.
What’s fun about this recipes, is that you an bake this zucchini casserole in a 8 x 8 casserole dish or in ramekins for individual servings.
If you’ve made your quota of zucchini breads and if you’re like me, had your fill of grilled, zucchini sautees I urge you to give this recipe a try.
Let’s take a look.
Ingredients You’ll Need
- Zucchini squash and Summer squash.
- Milk.
- Onion.
- Eggs.
- Cornmeal.
- Goat Cheese.
- Butter.
- Sugar.
- Olive oil.
- Dill, fresh or dried.
Ingredient Subs
- Goat Cheese: If you simply don’t like goat cheese, choose another cheese that will melt well and retain it’s creamy texture. Cream cheese, Manchego, Boursin or Emmental are good suggestions.
Step by Step Instructions
To Prepare The Squash
Simply wash the squash and then slice it about ¼ inch thick. There’s no need to remove the skin from the squash. The skin is totally edible and adds color to the casserole.
- Step 1: Preheat oven to 400 degrees. Heat a non-stick fry pan over medium high heat. Add the oil. Once the oil is hot, add the sliced squash and chopped onion. Cook until tender, stirring often, about 15 minutes.
- Step 2: Using a potato masher, mash the squash until partially mashed.
- Step 3: Add the goat cheese and butter and stir until cheese and butter are melted.
- Step 4: Mix in the cornmeal, eggs, milk, dill, sugar, salt, and pepper.
- Step 5: Stir until all ingredients are well blended.
- Step 6: Using a large spoon, fill individual ramekins with the squash mixture. Place the ramekins on a sheet pan.
- Step 7: Bake at 400 degrees for 35 minutes.
Tip: You can also bake this zucchini custard in an 8 x 8 baking dish.

- And we love it with Blue Cheese Burgers
This can be made up to a day in advance. Prep and prepare according to directions, but instead of baking, refrigerate covered tightly with foil.
Yes. Cover the individual ramekins or the casserole dish with plastic wrap. Freeze for up to 3 months. Let the casserole thaw in the refrigerator overnight before reheating.
Yes. The thickening agent here is corn meal rather than flour.
Pro Tip: Use a mandolin to slice the squash. This will insure that each slice is uniform in size and will cook evenly.
Storage:
Store any leftovers in an air-tight container, or in the original casserole or ramekin covered with plastic wrap. It will keep for 4 days.
Zucchini custard is best served straight from the oven. But for any leftovers, place in the microwave and reheat at 50% power in 30 second intervals. Or place in a 250 degree oven and let it slowly heat back up.
