Step‑by‑Step Instructions for Creamy Instant Pot Corn Casserole
Step 1: Prepare Instant Pot
Begin by adding 1 cup of water to the bottom of your Instant Pot. Place the trivet inside to create a steaming surface. This step is essential as it provides the moisture needed for cooking your Creamy Instant Pot Corn Casserole. Close the lid and set the pot to the “Saute” function briefly, just to warm it up.
Step 2: Grease Baking Pan
Take a 7-inch round cake pan and thoroughly grease it with butter or cooking spray, ensuring that you coat it well to prevent sticking. Next, wrap the pan tightly with aluminum foil to keep the steam inside during cooking. This will help the casserole achieve that desired fluffy texture once it’s complete.
Step 3: Mix Wet Ingredients
In a large mixing bowl, beat together the softened butter and sugar until the mixture becomes light and fluffy. This usually takes about 2-3 minutes. Once airy, add in the large egg and reduced fat sour cream, mixing until you achieve a smooth, creamy consistency that’s full of flavor for your casserole.
Step 4: Combine Dry
Now, it’s time to incorporate the dry ingredients. Gradually add half of the cornbread mix into the wet mixture, followed by the milk. Stir gently until just combined, then fold in the remaining cornbread mix. Be careful to avoid overmixing, as you want your Creamy Instant Pot Corn Casserole to remain tender and fluffy.
Step 5: Fold in Corn
Gently fold in both the whole kernel corn and the creamed corn into your batter, mixing until they are just incorporated. Aim for a homogenous mix without overworking the batter. This step adds the delightful sweetness and creaminess that makes the casserole a crowd-pleaser.
Step 6: Transfer and Cook
Pour the batter into your prepared pan, smoothing it out evenly across the top. Cover the pan loosely with aluminum foil, allowing some steam to escape. Carefully place the pan on the trivet inside the Instant Pot. Set the timer to cook on high pressure for 50 minutes, ensuring the lid is sealed.
Step 7: Release and Rest
Once the cooking time is complete, carefully perform a quick release of the pressure by turning the valve. When the steam has fully escaped, remove the lid and let your Creamy Instant Pot Corn Casserole stand for an additional 15 minutes. This resting period helps enhance the flavor and allows the casserole to set before you serve it.
