Directions

1. Preheat the Oven:
   Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil or cooking spray.

2. Prepare the Spinach Mixture:
   In a large skillet, heat olive oil over medium heat. Add chopped onion and sauté for 3–4 minutes, until softened. Stir in garlic and cook for 1 more minute until fragrant. Add the drained spinach and cook for another 2–3 minutes, stirring occasionally. Remove from heat and let it cool slightly.

3. Mix the Wet Ingredients:
   In a large bowl, whisk together sour cream, Greek yogurt, and eggs until smooth. Season with salt, pepper, and dried dill (if using).

4. Combine Everything:
   Add thawed hashbrowns, feta cheese, mozzarella, and the spinach mixture to the bowl. Stir until all ingredients are evenly distributed and well coated with the creamy mixture.

5. Assemble the Casserole:
   Spread the mixture evenly into the prepared baking dish. Smooth the top with a spatula and sprinkle with Parmesan cheese and a light dusting of paprika for color.

6. Bake to Perfection:
   Bake uncovered for 45–50 minutes, or until the top is golden brown and slightly crisp. The center should be set and bubbling around the edges.

7. Cool and Serve:
   Allow the casserole to rest for 10 minutes before serving. This helps the layers set and makes slicing easier.

Tips for the Perfect Hashbrown Casserole

• Thaw and Dry Your Hashbrowns: Excess moisture can make the casserole soggy. Make sure to thaw and pat dry before mixing.

• Balance Your Flavors: Feta can be salty, so taste the mixture before adding additional salt.

• Layer for Texture: For a crispier top, reserve some hashbrowns and cheese for the final layer before baking.

• Let It Rest: Allowing it to cool slightly after baking ensures clean slices and even texture.

• Use Quality Cheese: Freshly shredded cheese melts better and gives the casserole a rich, creamy consistency.

Frequently Asked Questions

1. Can I make this casserole ahead of time?

Yes, this dish is perfect for meal prep. You can assemble it the night before and refrigerate it until ready to bake. Just add 10 minutes to the baking time since it will be starting cold. It’s also great for freezing — simply wrap it tightly and store for up to 3 months.

2. Can I use fresh spinach instead of frozen?

Absolutely. Use about 4 cups of fresh chopped spinach. Sauté it lightly in a skillet until wilted, then squeeze out any excess moisture before mixing it into the casserole. Fresh spinach adds vibrant color and a slightly fresher taste.

3. What’s the best cheese combination for this casserole?

Feta gives the dish its signature tangy flavor, but blending it with mozzarella or Monterey Jack ensures creaminess and meltability. You can also experiment with Swiss or white cheddar for a different twist.

4. How do I keep the casserole from becoming watery?

The key is to drain both the hashbrowns and the spinach thoroughly. Squeeze out moisture using paper towels or a clean kitchen towel before adding them to the mixture. Baking uncovered also helps the top crisp up while allowing steam to escape.
