  • 2 pkg. frozen chopped spinach
  • 1/2 stick butter
  • 1 can cream of mushroom soup
  • 1/4 c. seasoned bread crumbs
  • 1/4 c. chopped pimentos
  • 1 pkg. green onion dip mix
  • 1/2 c. grated Cheddar cheese

Instructions

  3. Transfer the mixture to a buttered casserole dish.
  4. Bake at 350°F for 20 minutes, or until bubbly.

Tips & Substitutions

For an extra flavor boost, consider adding minced garlic or sautéed onions to the mixture. If you don't have pimentos, roasted red peppers work well as a substitute. You can also swap the Cheddar cheese for Monterey Jack or mozzarella for a different taste. Make sure to squeeze out as much water from the spinach as possible to avoid a watery dish.

Serving Suggestions

For a complete meal, consider adding a simple green salad or crusty bread on the side to complement the creamy flavors of the casserole.

Frequently Asked Questions

Can I use fresh spinach instead of frozen?

Yes, you can substitute fresh spinach for frozen. You'll need about 10-12 ounces of fresh spinach, which should be cooked down until wilted. Make sure to drain any excess moisture before adding it to the mixture to maintain the casserole's texture.

Is there a gluten-free option for the bread crumbs?

Absolutely! You can use gluten-free bread crumbs or crushed gluten-free crackers as a substitute for seasoned bread crumbs. This will allow you to enjoy the dish without gluten while still achieving that crunchy topping.

How can I make this dish vegetarian?

This recipe is already vegetarian, but to enhance the flavors, consider adding some sautéed mushrooms or bell peppers. These additions will complement the existing ingredients beautifully and add more depth to the dish.
