Ingredients

  • 1 lb. ground beef
  • 1 onion
  • 2 c. cottage cheese
  • 1/2 tsp. oregano
  • 1 (10 1/2 oz.) can cream of mushroom soup, undiluted
  • 1 c. sharp Cheddar cheese, shredded
  • 4 c. sliced zucchini
  • 1 c. uncooked instant rice
  • 1/2 tsp. salt
  • 1/8 tsp. pepper
  • 1 Tbsp. oil

Instructions

  1. Brown the ground beef and onion in oil.
  2. Add the uncooked instant rice and seasonings (oregano, salt, pepper).
  3. Stir for a few minutes and drain off excess grease.
  4. Layer in a 9 x 13-inch casserole dish: half the sliced zucchini, all of the meat mixture, cottage cheese, remaining zucchini, cream of mushroom soup, and shredded Cheddar cheese.
  5. Bake at 350°F (175°C) for 40 minutes or longer until hot and bubbly.

Tips & Substitutions

For a lighter version, you can substitute ground turkey for the beef and use low-fat cottage cheese. If zucchini is out of season, try using yellow squash or even spinach instead. To enhance flavor, consider adding garlic or diced bell peppers to the meat mixture. Ensure the rice is fully cooked by checking the moisture levels before layering, as the dish will absorb liquids during baking.

Serving Suggestions

This casserole is a complete meal on its own, but you can enhance it with a side salad or some crusty bread. Pair it with a light vinaigrette or a simple green salad to balance the richness of the dish. For a heartier option, serve with a side of roasted vegetables. It also pairs beautifully with 15 Minute Meat Loaf Midgets for a comforting dinner.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for about 2-3 minutes or until heated through. Alternatively, reheat in a preheated oven at 350°F (175°C) for about 15-20 minutes, covered with foil to retain moisture.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can assemble the casserole up to a day in advance. Cover it tightly with plastic wrap or aluminum foil and refrigerate. When ready to bake, remove the cover and add a few extra minutes to the baking time if it's cold from the fridge.

Can I freeze leftovers?

Absolutely! This casserole freezes well. Allow it to cool completely before transferring it to a freezer-safe container. It can be kept in the freezer for up to 3 months. To reheat, thaw in the refrigerator overnight and then bake at 350°F until heated through.

What can I use instead of cream of mushroom soup?

If you prefer a homemade option, you can create a simple white sauce using butter, flour, and milk, then add sautéed mushrooms for flavor. Alternatively, cream of chicken soup or even a vegetable broth can be used for a different taste profile.
