Heavenly creamed pearl onion casserole image

I love creamed onions but several years ago I decided to amp it up a bit by adding cheese and a breadcrumb topping & turning it into a casserole. I can guarantee you take 1 bite and you'll be humming, " heaven, I'm in heaven." lol

Time 1h

Number Of Ingredients 11

Ingredients

1 bag(s) 16 oz bag frozen bird's eye pearl onions, thawed
2 Tbsp unsalted butter
2 Tbsp flour
1-1/4 c hood's light cream
pinch salt and pepper, to taste
pinch ground mustard
dash(es) ground nutmeg
1-1/2 c good quality shredded, sharp white cheddar cheese
6 Tbsp melted butter
1-1/4 c italian style fine breadcrumbs
1 Tbsp fresh thyme, chopped

Steps:

1. Heat oven to 350. In a medium sized pot, melt 2 Tbsp butter over low heat. Whisk in the flour until smooth. Slowly whisk in the light cream. Increase heat to medium and cook & stir until thickened. Add salt & pepper to taste.
2. Add mustard and nutmeg. Add 1 cup of the cheese. Cook, stirring until cheese is melted. Stir in onions. Spoon into a 1 quart casserole dish.Sprinkle the top w/ remaining cheese.
3. In medium bowl, mix the 6 Tbsp melted butter and the breadcrumbs& chopped thyme until combined. Sprinkle over the cheese. Bake uncovered about 25-30 minutes or until bubbly and top is light golden brown.

Tips:

Use high-quality onions: Sweet onions are the best choice as they caramelize well and have a mild flavor.
Slice the onions thinly: This will help them cook evenly without burning.
Cook the onions slowly: This will allow them to develop a rich, caramelized flavor.
Use a heavy-bottomed pot: This will help distribute the heat evenly and prevent the onions from burning.
Add a splash of vinegar or white wine: This will help deglaze the pan and add a bit of acidity to the dish.
Season the casserole generously: Salt, pepper, garlic powder, and onion powder are all good choices.
Use a variety of cheeses: A combination of cheddar, Parmesan, and mozzarella will give you a nice gooey casserole.
Bake the casserole until it's bubbly and golden brown: This will ensure that it's cooked through and has a crispy top.
Let the casserole cool for a few minutes before serving: This will help it set and make it easier to slice.

Conclusion:

Heavenly Onion Casserole is a delicious and versatile dish that's perfect for any occasion. It's easy to make and can be tailored to your own taste preferences. So next time you're looking for a comforting and flavorful dish, give this casserole a try. You won't be disappointed!
