How to Make Zucchini Caprese Casserole

Ready to create this easy, nutritious recipe? Here’s a quick overview to guide you:

1. Preheat and prep: Preheat your oven to 400°F. Lightly grease an 8×8-inch (or similar-sized) baking dish with cooking spray.
2. Arrange the vegetables: Layer the zucchini and tomato slices in the baking dish like overlapping shingles. If needed, slice the vegetables in half to fit better.
3. Mix the seasoning: In a small bowl, combine the chopped shallot, ¼ cup basil, olive oil, salt, and pepper. Stir well.
4. Assemble the casserole: Spoon the shallot and basil mixture over the layered vegetables. Sprinkle the shredded mozzarella evenly on top.
5. Bake to bubbly perfection: Bake for about 30 minutes, or until the vegetables are tender, and the cheese is melted and starts to brown slightly.
6. Finish and serve: Sprinkle the remaining 2 tablespoons of basil on top for a finishing touch. For extra flavor, drizzle with balsamic vinegar just before serving.

Simply Nourished Cooking Tips

For a perfectly cooked and flavorful zucchini caprese casserole, keep these helpful tips in mind:

• Drain excess moisture: If your zucchini and tomatoes are extra juicy, lightly pat them dry with paper towels before layering to avoid excess liquid in the casserole.
• Cheese options: Fresh mozzarella is classic, but if you prefer something sharper, try sprinkling in a little parmesan for added flavor.
• Basil freshness: Always add fresh basil at the end to preserve its vibrant flavor and color.
• Serving ideas: Pair this casserole with a side of crusty whole-grain bread or a simple green salad for a complete meal.

Variations and Storage Tips

Want to customize or save leftovers? Here’s how:

Recipe Variations:

• Add protein: Sprinkle in cooked chicken, turkey sausage, or white beans for an extra boost of protein.

• Experiment with veggies: Add eggplant slices, roasted red peppers, or mushrooms for added variety.

Storing & Reheating:

• Refrigerate: Store cooled casserole in an airtight container for up to 3 days in the fridge.
• Freeze: Freeze individual portions in freezer-safe containers and reheat in the oven for best results.
