Hamburger Zucchini Bake

This simple Hamburger Zucchini Bake recipe is one of my favorite main dishes to make when I have zucchini on hand. It’s inexpensive, delicious and easy!

  • ½ lb. ground beef
  • ½ onion, finely diced
  • 1 c. Bisquick (see Notes below)
  • ½ c. shredded Parmesan cheese
  • 4 eggs
  • ¼ c. canola oil
  • 1 tsp. parsley
  • ½ tsp. salt
  • ½ tsp. basil
  • ¼ tsp. garlic powder
  • ¼ tsp. black pepper
  • 3 ½ c. shredded zucchini, drained (see Notes below)
  • tomatoes, sliced thin


  • Brown ground beef and onion.
  • Mix all ingredients except zucchini and tomatoes in a bowl.
  • Stir in zucchini and pour into a greased 2 ½ to 3 quart baking dish.
  • Top with tomatoes. (This knife is my absolute favorite for slicing tomatoes! It cuts through them like their butter.)
  • Bake at 350° for 40 to 50 minutes or until center is set and top is lightly browned.


  • I love using my Homemade Bisquick for this!
  • Make sure zucchini is drained well.  Either put it in a colander or sieve, then squish out as much excess moisture as possible.  If you don’t do this, your casserole will not set up!
  • How you long you need to bake this depends on how deep your baking dish is.  My dish is fairly small and makes a thick casserole, so I need to bake it at least 50 minutes.  However if your dish is more shallow, you will need to reduce the baking time.
