Ingredients in Weight Watchers Breakfast Casserole
- 6 large eggs: Eggs create the base for this Weight Watchers Breakfast Casserole and provide a rich flavor.
- 1 cup diced ham: Ham adds a salty punch to the recipe. I recommend using a good quality diced ham like Frick’s for this rather than cutting up sliced deli meat.
- 1/2 cup 1% milk: Milk adds moisture and creaminess to the casserole and helps to make the eggs more fluffy.
- 1 1/2 cups frozen diced Potatoes O’Brien: Frozen diced potatoes add texture to the dish and convenient bite-sized pieces of onions and bell peppers.
- 1/4 teaspoon sea salt: Salt enhances the flavors in the casserole.
- 1/2 teaspoon seasoned salt: Seasoned salt is a blend of salt and spices that quickly adds lots of flavor to the potatoes.
- 1/8 teaspoon ground black pepper: Pepper provides a subtle heat that juxtaposes the creaminess of the eggs, milk, and cheese.
- 1 cup shredded reduced-fat cheddar cheese: Cheddar provides a sharp bold taste and gooey texture that gives this breakfast casserole a comfort food feel.

Preheat and Prepare Pan
Preheat the oven to 375°F. Spray an 8-inch square baking pan with cooking spray and set aside. Sprinkle the seasoned salt on top of the potatoes and toss to coat.

Whisk Eggs and Milk
Crack open the eggs into a large bowl. Pour in the milk and whisk until well combined and foamy.

Season Egg Mixture
Sprinkle the eggs with sea salt and pepper and whisk until well combined.

Add Ham and Potatoes
Add the ham and seasoned potatoes to the bowl and gently stir.

Pour Mixture into Pan
Pour the egg mixture into the prepared pan.

Top with Cheese and Bake
Top with cheese and place into the oven for 30-35 minutes.

Check for Doneness
When done, the eggs should have an internal temperature of at least 160°F and feel firm to the touch. The center should not look wet. Let cool for 10 minutes then slice and serve warm.

Variations and Substitutions
- Add turkey sausage: Swap diced ham for cooked and crumbled turkey breakfast sausage for a savory twist.
- Swap milk for cottage cheese: Blend eggs and cottage cheese for a denser, creamier texture.
- Use tater tots: Substitute diced potatoes with cooked tater tots or crispy crowns for added crunch.
- Opt for no cheese: Reduce points by omitting cheese, or customize with mozzarella or feta before serving.
- Points to spare?: Enhance flavor with chicken or pork sausage, or add cut-up bagel thins for a bread-like texture.

Tips and Tricks for Making Weight Watchers Breakfast Casserole
- Use room temperature eggs: They whisk more easily. Let them sit at room temperature for 30 minutes or submerge in warm water for 10 minutes.
- Incorporate air into the eggs: Use a whisk or electric beater to make the eggs fluffy and the dish more voluminous.
- Season the potatoes: Seasoning before adding to the casserole enhances flavor. Defrost slightly so seasoned salt sticks better.
- Reheating tips: Microwave for 45-60 seconds or use an air fryer at 300°F for 5-7 minutes. Reduce heat if the top cooks too quickly in the air fryer.
