Gluten-Free Corn Casserole Recipe for a Classic Side Dish

Sweet corn, sour cream, honey, and fine cornmeal come together in a tender, sweet-and-savory side dish. This gluten-free corn casserole uses both creamed corn and drained whole-kernel corn, with a simple batter that goes straight into the oven. Prep takes 5 minutes, baking takes 45 minutes, and the 50-minute recipe makes 9 servings.

Why Make This Gluten-Free Corn Casserole

A tender cornmeal batter brings together two kinds of sweet corn for a casserole with a soft, hearty texture and a gently sweet-and-savory flavor. Sour cream, honey, and melted butter are mixed with the eggs and corn, while the dry ingredients are whisked separately before everything is folded together. These straightforward steps make the batter simple to prepare without adding complicated techniques. Baked in a familiar casserole format, it makes a practical gluten-free side dish with clearly defined portions: the recipe yields 9 servings. The combination of cornmeal and whole kernels also gives the dish a distinct corn-forward character in each serving.

Ingredients for Gluten-Free Corn Casserole

The ingredients are divided into a dry mixture, a wet mixture, and two types of corn. Together, they make a tender cornmeal batter with a sweet-and-savory flavor.

Dry Mixture

• 1/2 cup gluten-free all-purpose flour: Use a 1:1 gluten-free replacement to form the base of the batter.
• 1/2 cup fine gluten-free cornmeal: Fine cornmeal blends into the batter and gives the casserole its cornmeal character.
• 3 tablespoons granulated sugar: Adds sweetness to balance the savory ingredients.
• 2 teaspoons baking powder: Whisk it with the flour and cornmeal so it is evenly distributed through the batter.
• 1/2 teaspoon salt: Rounds out the mixture’s flavor.

Wet Mixture

• 8 tablespoons unsalted butter, melted: Mix it with the other wet ingredients before adding the dry mixture.
• 2 tablespoons pure honey: Adds another layer of sweetness to the sweet-and-savory casserole.
• 1 cup sour cream: Combines with the eggs and butter to form the wet base of the tender batter.
• 2 large eggs: Help bind the wet ingredients and corn together.

The Two Kinds of Corn

• 1 (15-ounce) can creamed corn: Stir it into the wet mixture to bring corn flavor throughout the casserole.
• 1 (15-ounce) can whole-kernel sweet corn, drained: Drain the kernels before adding them so excess liquid does not go into the batter. They add whole pieces of sweet corn alongside the creamed corn.

How to Make Gluten-Free Corn Casserole

Prepare the dry and wet mixtures separately, then combine them and bake the batter in a greased 9-by-9-inch dish. Follow these steps to make the casserole, checking that the center is set before it cools.

Whisk Together the Dry Ingredients

Preheat the oven to 350°F. In a mixing bowl, whisk together the gluten-free all-purpose flour, fine gluten-free cornmeal, granulated sugar, baking powder, and salt. Mixing these ingredients before adding them to the wet mixture distributes the baking powder and salt throughout the dry ingredients. Set the bowl aside while you prepare the wet ingredients and corn.

Mix the Wet Ingredients and Corn

In a large bowl, mix the melted butter with the honey, sour cream, and eggs. Stir in the creamed corn and the drained whole-kernel corn so both kinds of corn are incorporated into the wet mixture. Drain the whole-kernel corn before adding it, as directed in the recipe. The prepared bowl will hold the wet ingredients and corn before the dry mixture is folded in.

Combine the Batter and Prepare the Dish

Fold the dry ingredients into the wet mixture until just combined. Once the batter comes together, grease a 9-by-9-inch baking dish with butter or nonstick spray. The recipe recommends this dish size for baking the casserole. Have it prepared before you pour in the batter so the mixture can go directly into the dish.

Fill the Dish and Bake

Pour the batter into the greased baking dish and bake at 350°F for 45 minutes. The casserole is ready when the center is set. Keep the oven temperature and baking time as stated, and use the set center as the doneness cue. When baking is complete, remove the dish from the oven and allow the casserole to cool before serving.

Cool Before Serving

Let the casserole cool for about 10 minutes before serving. This brief resting time is part of the recipe’s instructions after baking. Once the cooling period has passed, serve the casserole as a side dish.

Gluten-Free Ingredient Checks and Recipe Tips

Check the labels on the gluten-free all-purpose flour, cornmeal, and baking powder, and use products identified as certified gluten-free. The recipe specifically calls for a 1:1 gluten-free flour replacement and fine gluten-free cornmeal; choosing those ingredients keeps the quantities and ingredient types aligned with the recipe. Also check the labels on both cans of corn, as the recipe notes this as part of its gluten-free ingredient checks.

Drain the whole-kernel corn before stirring it into the wet ingredients. This is a simple but important preparation step, since the recipe calls for drained kernels rather than adding the can liquid to the batter. The creamed corn is added as is.

Use a 9-by-9-inch baking dish, the size recommended for this casserole. Grease it with butter or nonstick spray before pouring in the batter, then bake as directed until the center is set. These label and preparation reminders follow the recipe’s instructions without changing its ingredients or method.

Serving and Yield

This gluten-free corn casserole is categorized as a side dish and makes 9 servings. The yield refers to the full casserole divided into nine portions, making it easy to plan how much to prepare for a meal. Since the recipe’s ingredients and baking method are set for a 9-by-9-inch baking dish, use that recommended size as you prepare it.

After baking, let the casserole cool for about 10 minutes before serving. This gives it time to rest in the dish before you portion it. Serve once the cooling period is complete, keeping the recipe’s intended role as a side dish in mind.
