Instructions

Preheat Oven: Preheat your oven to 350 degrees Fahrenheit to get it ready for baking the casserole evenly.
Combine Ingredients: In a large bowl, mix together frozen hash browns, cubed ham, shredded cheddar cheese, halved cherry tomatoes, chopped green bell pepper, chopped yellow onion, and minced garlic until well combined. Spray a 9×13 inch baking dish with cooking spray and pour the mixture into the dish spreading evenly.
Prepare Egg Mixture: In a separate large bowl (or reuse the same bowl after step 2), whisk together the 12 large eggs, 1 cup of milk, 1 teaspoon salt, and ½ teaspoon ground black pepper until fully blended and slightly frothy.
Pour Egg Mixture: Pour the egg mixture evenly over the hash brown mixture in the baking dish and gently press down with the back of a wooden spoon to compact the ingredients and help everything bind together during baking.
Bake the Casserole: Place the baking dish in the preheated oven and bake for 1 hour, or until the center is set and the edges turn golden brown and crispy.
Rest and Serve: Remove the casserole from the oven and let it rest for 10 minutes before slicing. This helps it set further and makes it easier to serve.

Notes

Make sure to spray the baking dish well with cooking spray to prevent sticking.
For added flavor, consider adding diced green chilies or a dash of smoked paprika.
Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
This casserole can be made the night before by assembling it and refrigerating it before baking.
To make it gluten-free, verify that your frozen hash browns and ham do not contain any gluten additives.
