Print Recipe

A quick and comforting breakfast casserole combining fresh summer tomatoes, sweet corn, and sharp cheddar cheese for a hearty yet light start to your day.

Ingredients

Scale
  • 8 large eggs, room temperature
  • 1 cup (240 ml) whole milk or 2%
  • 1 ½ cups fresh corn kernels (about 3 ears of corn), cut from the cob
  • 2 large ripe summer tomatoes, diced
  • 1 ½ cups shredded sharp cheddar cheese
  • ½ medium yellow onion, finely diced
  • 2 cloves garlic, minced
  • 2 tablespoons fresh basil, chopped (optional)
  • Salt and pepper to taste
  • 1 tablespoon olive oil or butter
  • ½ cup breadcrumbs or crushed crackers (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease your 9×13 inch baking dish with butter or oil to avoid sticking.
  2. Heat 1 tablespoon olive oil or butter in a skillet over medium heat. Add diced onion and cook for 4-5 minutes until translucent. Add minced garlic and sauté for another 30 seconds until fragrant. Remove from heat and set aside.
  3. Dice the tomatoes and cut the corn kernels from the cob. Chop fresh basil if using.
  4. In a large bowl, whisk together 8 eggs and 1 cup (240 ml) milk until smooth. Season with about ½ teaspoon salt and ¼ teaspoon black pepper.
  5. Add the sautéed onion and garlic, diced tomatoes, corn kernels, chopped basil, and shredded cheddar cheese to the egg mixture. Stir gently to combine evenly.
  6. Pour the mixture into the prepared baking dish, spreading evenly. Sprinkle ½ cup breadcrumbs or crushed crackers on top if desired.
  7. Bake for 35-40 minutes until the casserole is puffed, golden brown on top, and a knife inserted in the center comes out clean.
  8. Let the casserole rest for 5-10 minutes before slicing and serving.

Notes

If the top browns too quickly, tent loosely with foil halfway through baking. Drain tomatoes if very juicy to avoid sogginess. Room temperature eggs yield a fluffier texture. Sauté onions and garlic for better flavor. Can be made gluten-free by omitting breadcrumbs or using gluten-free crackers. Dairy-free options available with plant-based cheese and milk.
