13 Flavorful Summer Vegetable Casseroles Packed With Garden Produce

Summer gardens often give you more zucchini, tomatoes, and peppers than you can use at once. Casseroles make a simple way to cook them into complete meals without extra steps. These recipes focus on everyday ingredients and straightforward prep. You will find options that work for weeknights or when you need to use up what is fresh. Each one keeps the vegetables as the main part of the dish.

Helpful Tips Before You Start

Fresh summer vegetables release a lot of water during cooking. These steps help keep casseroles firm and full of flavor.

Salt High Moisture Vegetables

Zucchini, eggplant, and summer squash turn watery in the oven. Salt the slices, let them drain for 15 to 20 minutes, then pat them dry.

Cut Vegetables to Similar Sizes

Even pieces cook at the same rate. Aim for half inch slices or cubes so nothing turns mushy while other parts stay firm.

Use a Hot Oven and Uncovered Pan

A 375 to 400 degree oven with the dish uncovered helps excess moisture evaporate. This keeps the top browned instead of steamed.

Taste and Adjust Seasoning Late

Garden vegetables vary in sweetness and salt content. Check the casserole in the last 10 minutes and add more salt, pepper, or fresh herbs if needed.

Mediterranean Eggplant and Zucchini Casserole with Feta and Olives
