Ingredients

  • 4 to 5 cups zucchini, sliced 1/4-inch thick
  • 1 1/2 cups Bisquick
  • 1 1/2 cups Cheddar cheese, shredded
  • 1/4 cup onion, chopped
  • 1/2 cup vegetable oil
  • 3 eggs
  • 1 teaspoon oregano
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 (8 oz.) can tomato sauce

Instructions

  1. Combine all ingredients except tomato sauce and mix together in a large bowl.
  2. Place the mixture into a greased 9 x 11-inch glass baking dish.
  3. Pour tomato sauce on top.
  4. Bake at 350°F (175°C) for 40 minutes or until set.

Tips & Substitutions

For a different flavor, try adding chopped bell peppers or mushrooms to the mix. If you don't have Bisquick, you can substitute with a homemade baking mix using flour, baking powder, and salt. To reduce the moisture from the zucchini, consider salting the slices and letting them sit for 30 minutes before mixing. This adds a nice depth of flavor and helps prevent a soggy casserole.

Serving Suggestions

This zucchini casserole pairs beautifully with a fresh garden salad or crusty bread for a complete meal. Consider serving it alongside grilled chicken or a light protein for a balanced dinner. For a heartier option, try it with a side of roasted vegetables. It's also a great vegetarian dish that can be enjoyed as a main course.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply place the casserole in a preheated oven at 350°F (175°C) for about 15-20 minutes until heated through. You can also microwave individual portions on medium power for quicker reheating.

Frequently Asked Questions

Can I use frozen zucchini instead of fresh?

While fresh zucchini is preferred for texture, you can use frozen zucchini in a pinch. Just be sure to thaw and drain any excess moisture before mixing it into the casserole to avoid a watery result.

Is it possible to make this dish ahead of time?

Absolutely! You can prepare the casserole the night before, cover it, and refrigerate it until you're ready to bake. Just add a few extra minutes to the baking time if it's going into the oven cold.

What can I use instead of cheddar cheese?

If you prefer a different cheese, mozzarella or Monterey Jack can work well in this recipe. For a sharper flavor, consider using Gouda or a combination of cheeses. Just ensure the cheese is shredded for even melting.
