- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 8 ounces cooked ham, diced
- 1 green bell pepper, diced
- 1 small yellow onion, diced
- 1 cup diced mushrooms
- 1 1/2 cups shredded cheddar cheese
- 1 cup shredded Monterey Jack cheese
- 2 tablespoons chopped fresh parsley
- 1 tablespoon butter or olive oil, for greasing the dish
Optional Additions
- 1/2 cup diced red bell pepper
- 1 cup fresh spinach
- 1/2 teaspoon smoked paprika
- 2 green onions, sliced
- 1/4 cup grated Parmesan cheese
How to Make Farmer’s Casserole
1. Prepare the Baking Dish
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch glass baking dish with butter or olive oil.
Using a glass casserole dish makes this recipe especially convenient because you can assemble, bake, and serve everything in the same dish.
2. Prepare the Vegetables
Heat a large skillet over medium heat.
Add the diced onion, green bell pepper, and mushrooms. Cook for approximately 5–7 minutes, stirring occasionally, until the vegetables soften.
If you’re adding spinach, stir it in during the final minute of cooking and allow it to wilt.
Remove the skillet from the heat.
3. Prepare the Egg Mixture
In a large bowl, whisk together the eggs, milk, Dijon mustard, garlic powder, onion powder, salt, and black pepper.
Whisk until the eggs are completely blended and the mixture is smooth.
For a richer casserole, you can replace 1/2 cup of the milk with heavy cream.
4. Build the Casserole
Spread the thawed hash brown potatoes evenly across the bottom of the prepared baking dish.
Scatter the diced ham over the potatoes.
Add the sautéed green peppers, onions, and mushrooms.
Sprinkle the cheddar and Monterey Jack cheese evenly over the vegetables.
Pour the egg mixture slowly over everything, making sure it reaches all areas of the casserole.
Sprinkle fresh parsley over the top.
5. Bake
Cover the dish loosely with aluminum foil and bake for 30 minutes.
Remove the foil and continue baking for another 20–25 minutes, or until the eggs are completely set and the cheese is melted and lightly golden.
The center should no longer jiggle when the casserole is gently moved.
If you want an extra-golden cheese topping, place the casserole under the broiler for 1–2 minutes at the end. Watch carefully to prevent burning.
6. Rest Before Serving
Remove the casserole from the oven and allow it to rest for 10 minutes.
This helps the egg mixture finish setting and makes the casserole easier to cut into neat portions.
Slice into squares and serve warm.

Tips for the Best Farmer’s Casserole
Thaw the Hash Browns
Thawing the frozen potatoes before assembling the casserole helps them cook evenly and prevents excess moisture from making the dish watery.
For even better texture, pat the thawed potatoes dry with paper towels.
Use Different Cheeses
Cheddar and Monterey Jack create a creamy, flavorful topping, but you can easily use mozzarella, Colby, Swiss, pepper Jack, or a Mexican cheese blend.
Don’t Overbake
Overbaking can make the eggs rubbery. Remove the casserole when the center is just set and allow it to rest before slicing.
Dice Everything Evenly
Cutting the ham and vegetables into similarly sized pieces helps distribute the ingredients throughout the casserole and makes every serving more balanced.
Easy Variations
Sausage Farmer’s Casserole
Replace the ham with 1 pound cooked breakfast sausage. Brown the sausage thoroughly and drain excess grease before adding it to the casserole.
Bacon Version
Use 8 slices cooked and crumbled bacon instead of ham for a smoky, crispy variation.
Vegetable Farmer’s Casserole
Leave out the meat and add extra vegetables such as zucchini, tomatoes, spinach, mushrooms, or broccoli.
Spicy Breakfast Casserole
Use pepper Jack cheese and add 1 diced jalapeño or 1/2 teaspoon crushed red pepper flakes.
Loaded Potato Version
Add cooked bacon, extra cheddar, green onions, and a little sour cream after baking for a loaded baked-potato-inspired casserole.
What to Serve with Farmer’s Casserole
This hearty casserole can be served as a complete breakfast, but several simple sides pair beautifully with it.
Serve it with:
- Fresh fruit salad
- Sliced strawberries and blueberries
- Toast or English muffins
- Buttermilk biscuits
- Fresh green salad
- Roasted tomatoes
- Avocado slices
- Fresh salsa
For a weekend brunch, serve the casserole alongside fresh fruit and coffee for an easy and satisfying spread.
Make-Ahead Instructions
One of the best things about Farmer’s Casserole is that you can prepare it ahead of time.
Assemble the entire casserole in the glass baking dish, cover it tightly, and refrigerate for up to 24 hours before baking.
When you’re ready to cook, remove it from the refrigerator while the oven preheats.
Because the casserole starts cold, you may need to add approximately 5–10 minutes to the baking time.
This makes it an excellent holiday breakfast casserole because most of the preparation can be completed the night before.
Storage and Reheating
Store leftover casserole in an airtight container or cover the baking dish tightly and refrigerate for up to 3–4 days.
Individual portions can be reheated in the microwave for about 60–90 seconds, depending on the portion size.
For larger portions, reheat in a 350°F oven until warmed through.
The casserole can also be frozen in individual portions for up to 2 months. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use fresh potatoes instead of frozen hash browns?
Yes. Dice about 1 pound of potatoes into small pieces and parboil them for 5–7 minutes before adding them to the casserole.
You can also roast the diced potatoes until lightly golden before assembling the dish.
Can I use leftover ham?
Absolutely. This is a great recipe for using leftover holiday ham. Simply dice the cooked ham and add it directly to the casserole.
Can I make Farmer’s Casserole without meat?
Yes. Omit the ham and add additional vegetables such as mushrooms, spinach, broccoli, or bell peppers.
Can I use a different baking dish?
A 9×13-inch glass baking dish is ideal, but a similar-sized ceramic or metal casserole dish will also work. Baking times may vary slightly depending on the material and depth of the dish.
Why is my casserole watery?
Excess moisture usually comes from vegetables or thawed potatoes. Drain vegetables well and pat thawed hash browns dry before assembling the casserole.
