Swiss Medley Casserole is a comforting and easy-to-make dish that combines creamy mushroom soup, tangy sour cream, and melted Swiss cheese with a medley of vegetables. Topped with buttery crushed crackers, it bakes to a golden, crispy finish perfect for weeknight dinners or potlucks.

Ingredients
- 1 (12 oz) bag frozen vegetable medley, defrosted
- 1 (10 oz) can condensed cream of mushroom soup
- ½ cup sour cream
- 1 cup shredded Swiss cheese
- ½ teaspoon black pepper
- 1 sleeve Ritz crackers, crushed
- ¼ cup butter, melted
Instructions
- Step 1: Preheat your oven to 425 degrees F and lightly grease an 8×8-inch baking dish.
- Step 2: In a large bowl, combine the sour cream, condensed cream of mushroom soup, shredded Swiss cheese, and black pepper, mixing well.
- Step 3: Gently fold in the defrosted vegetable medley until evenly coated with the creamy mixture.
- Step 4: Transfer the mixture into the prepared baking dish, spreading it out evenly.
- Step 5: Sprinkle the crushed Ritz crackers evenly over the top, then drizzle the melted butter over the crackers to help them crisp up.
- Step 6: Bake in the preheated oven for 23-25 minutes, or until the top is golden brown and bubbly. Serve hot.
Tips & Variations
- For extra flavor, add a teaspoon of garlic powder or onion powder to the creamy mixture before baking.
- Try substituting Swiss cheese with Gruyère or mozzarella for a different cheesy taste.
- Use fresh vegetables instead of frozen; lightly steam them beforehand to keep the casserole from becoming watery.
- If you prefer a crunchier topping, toss crushed crackers with a tablespoon of grated Parmesan before sprinkling.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm in the oven at 350 degrees F for 10-15 minutes to maintain the crispy topping, or microwave on medium power until heated through.
