Ingredients

  • 2 (16 oz.) cans peeled whole tomatoes
  • 1 large onion, chopped
  • 4 Tbsp. margarine
  • 2 Tbsp. granulated sugar
  • 1 tsp. salt
  • 1 tsp. oregano
  • 2 or 3 slices bread, crumbled
  • 3/4 cup sharp Cheddar cheese, grated

Instructions

  1. Put the tomatoes and onion in a saucepan; bring to a boil.
  2. Add margarine, sugar, salt, and oregano.
  3. Reduce heat to medium and cook for 5 minutes.
  4. Add bread and stir.
  5. Pour into a 1 1/2-quart lightly greased casserole dish.
  6. Top with grated cheddar cheese.
  7. Bake, uncovered, at 325°F for 20 minutes or until cheese is melted.

Tips & Substitutions

For added flavor, consider sautéing the onions in olive oil instead of margarine, or experiment with different herbs like basil or thyme. If you want a crunchier texture, you can use day-old bread instead of fresh. For a lighter version, replace some of the cheddar cheese with a low-fat variety. This dish is great for using up pantry staples, making it a perfect choice for quick weeknight meals.

Serving Suggestions

Serve this Tomato Casserole as a main dish alongside a fresh green salad or steamed vegetables for a balanced meal. It pairs beautifully with American recipes like Corncake or Large Broccoli Casserole. For a complete dinner, consider adding garlic bread or a creamy coleslaw as side dishes to enhance the overall flavor experience.

Storage & Reheating

Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, place in the oven at 325°F for about 15 minutes until warmed through, ensuring the cheese doesn’t dry out. You can also microwave individual portions for about 1-2 minutes, but the oven method will keep the topping crispy.
