How To Make Zucchini Sausage Casserole

This is one of the easiest dinners to prepare in less than 30 minutes and such a perfect way to use many zucchini that often take over your veggie garden in summer.

Ingredients

All you need to make this zucchini casserole are:

  • Fresh Zucchinis – Trim the ends and keep them unpeeled to save all the vitamins and nutrients.
  • Olive Oil
  • Onion
  • Bell Pepper – any color, green or red are my favorite options
  • Garlic
  • Ground Italian Sausage – I suggest chicken sausage meat to cut down the fat or any ground sausage meat you love, like pork or turkey. You can use plant-based meat if you prefer.
  • Italian Seasoning
  • Salt
  • Ground Pepper
  • Diced Tomatoes form a can, undrained
  • Worcestershire Sauce
  • Shredded Mozzarella
  • Shredded Cheddar
  • Broth or you can use any kind of broth from beef broth to vegetable broth

Preparation

First, trim the zucchini ends, and using a long sharp knife, slice the zucchini crosswise into thin slices of about 1/4 of an inch.

Set aside in a large bowl.

Preheat the oven to 400°F (200°C). Lightly spray a baking dish with cooking spray. Set aside.

Cooking The Meat

In a large skillet, warm olive oil over medium-high heat. Then, add diced onion and garlic. Cook until fragrant, then stir in sausage, Italian seasoning, salt, and pepper.

Cook sausage over medium heat until the meat is no longer pink, breaking the meat with a spoon to form a small ground.

Stir in the diced bell pepper, Worcestershire sauce, and cook until bell pepper softens – about 1 to 2 minutes.

Remove from heat, and place the cooked sausage mixture on a plate.

Meanwhile, in the same skillet add the remaining oil and add the zucchini slices. Cook and stir for 1 minute then add diced canned tomatoes – undrained – and broth.

Reduce the heat and cook until the zucchini softens – about 5 to 7 minutes.

In the end, return the cooked sausage mixture to the pan and stir to combine.

Pour the entire mixture into the prepared baking dish. Sprinkle both cheeses on top of the dish.

Bake at 400°F (200°C) for 10 to 15 minutes or until bubbly and the cheese has melted.

Storage Instructions

The great thing about casseroles is how long they store in the fridge or freezer. You can keep this casserole refrigerated for up to 3 days. Cover the dish with foil.

You can also place portions in airtight containers and freeze them for up to one month. Thaw in the fridge the day before and rewarm in a microwave-safe container or non-stick saucepan.

Allergy Swaps

Below are some ideas to make this recipe with a few variations if you need them.

  • Meat-Free – There are plenty of plant-based ground meat options that are made from natural ingredients and not overly processed. Otherwise, try rehydrated textured soy protein, lentils, or tofu crumble.
  • Low-Sodium – You can use low-sodium broth or replace it with water.
  • Zucchini – You can also use round yellow squash for this recipe.
  • Dairy-Free – Feel free to use any dairy-free grated cheese alternatives you love.
  • Green Bell Pepper Swap – You can replace the bell pepper with sliced button mushrooms or simply skip it.

Frequently Asked Questions

Below are my answers to your most common questions about this recipe.

How Do I Keep Sausages From Sticking To My Cast-Iron Skillet?

You must use oil to cook sausage meat in your cast iron, or it will stick badly to the surface.
Heat a tablespoon of your favorite cooking oil, like avocado oil or olive oil, before adding the meat to the skillet.

How Long Should I Cook The Sausages In Iron Skillet?

You know the sausages are cooked when the meat in the center is no longer pink.
Depending on the thickness of the sausage, or if you break the sausage meat with a spoon, it can take from 6 to 10 minutes to cook.

What Flavors Go Well With Sausage?

Sausage goes well with Italian flavors like basil, Parsley, Parmesan, or marinara sauce.

What Sauces Go Well On Italian Sausage?

Italian sausage goes well with tomato-based sauce, or cream cheese garlic sauce.
