Ingredients

  • 12 oz. frozen shredded hash browns
  • 1 c. shredded Cheddar cheese
  • 1 Tbsp. flour
  • 1/4 c. chopped onion
  • 1 tsp. salt
  • 1/4 tsp. pepper
  • 1 Tbsp. dried chives

Instructions

  1. Pierce the frozen hash brown potato package.
  2. Cook the potatoes in the microwave for 3 to 4 minutes, rotating one quarter turn halfway through cooking.

Tips & Substitutions

To enhance flavor, consider adding diced bell peppers or mushrooms, which can complement the cheesy richness. If you don't have Cheddar cheese, any melty cheese like Monterey Jack or Gouda would work well. For a gluten-free option, substitute the flour with cornstarch. When microwaving, ensure the hash browns are evenly spread for consistent cooking.

Serving Suggestions

This cheesy potato casserole is a fantastic side dish for breakfast or brunch, pairing wonderfully with scrambled eggs or bacon. For lunch or dinner, serve it alongside a fresh salad or the Macaroni Apple Salad for a delightful contrast in textures. Top with fresh chives or a dollop of sour cream for extra creaminess.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave in 30-second intervals until heated through, or place in an oven-safe dish and bake at 350°F for about 15 minutes for a crispy top. This dish also freezes well; just make sure it cools completely before freezing.

Frequently Asked Questions

Can I use fresh potatoes instead of frozen hash browns?

Yes, you can use fresh potatoes. Peel and grate them, then par-cook in the microwave for about 5-7 minutes before mixing with other ingredients. Keep in mind that the texture may vary slightly from using frozen hash browns.

What can I add to make this casserole more filling?

To make the casserole more filling, consider adding cooked protein such as diced ham, bacon, or shredded chicken. You could also mix in steamed broccoli or spinach for added nutrition and flavor. This can transform it into a hearty main dish.

Can I make this casserole ahead of time?

Absolutely! You can prepare the casserole up to a day in advance. Assemble the ingredients, cover tightly, and refrigerate. When ready to bake, simply remove from the refrigerator and follow the cooking instructions, adding a few extra minutes if starting from cold.
