Step-by-Step Instructions
Preparing the Base
Start by beating together the softened butter and sour cream in a small bowl until smooth. Then, add the egg and mix until well combined. In another bowl, whisk together the flour, baking powder, salt, and sage. Gradually incorporate the dry mixture into the creamed mixture, stirring just until combined.
Mixing the Filling
In a large bowl, combine the thawed vegetables, chicken, condensed soup, and chopped onion. Mix well to ensure all ingredients are evenly distributed. This filling packs in flavor and nutrition!
Assembling the Casserole
Spread the creamed base evenly into a greased 3-quart baking dish. Pour the vegetable and chicken mixture over the creamed base, ensuring it’s evenly distributed. Finally, sprinkle the shredded cheddar cheese on top for a deliciously gooey finish.
Baking Instructions
Bake the casserole uncovered in a preheated oven at 400°F for 35 to 40 minutes. You’ll know it’s ready when it’s heated through and bubbling, creating a golden, crispy top that’s hard to resist.
Tips for Perfecting Your Casserole
Storage Guidelines
This casserole can be stored in the refrigerator for 3 to 4 days after cooling. Reheat in the microwave or a 325°F oven until hot. It’s perfect for meal prep!
Freezing Considerations
While freezing is not generally recommended due to potential changes in the consistency from the dairy ingredients, you can adjust the recipe for fresh enjoyment each time.
Vegetarian and Gluten-Free Modifications
If you’re looking for a vegetarian option, simply omit the chicken and load up on more vegetables like mushrooms and zucchini. For a gluten-free version, substitute the flour and condensed soup with suitable alternatives.
