Ingredients

  • 1 Tbsp butter
  • 3 cups sweet onion
  • 1 Tbsp flour
  • 1 1/4 cups milk
  • 2 eggs
  • 1/2 Tbsp salt
  • pepper to taste
  • 1/2 lb sharp cheddar cheese grated
  • 1 pie shell

Instructions

  1. Saute onion in butter until soft.
  2. Mix flour with cold milk until there are no lumps.
  3. Add eggs, salt, pepper, and cheese to the milk mixture and blend well.
  4. Add the sautéed onions to the mixture and mix thoroughly.
  5. Pour the mixture into the pie shell.
  6. Bake at 350 degrees Fahrenheit for 40 minutes until the pie is browned and set.

Tips & Substitutions

For a richer flavor, try using Vidalia or Walla Walla sweet onions. If you're short on time, pre-sautéed onions can save you about 10 minutes. You can substitute half-and-half for milk for a creamier filling. If you prefer a gluten-free option, use a gluten-free flour blend in place of regular flour.

Serving Suggestions

Sweet Onion Pie is delicious on its own but pairs beautifully with a fresh green salad or roasted vegetables for a balanced meal. Consider serving it alongside a light soup, such as a tomato bisque, for a comforting lunch. This dish also makes a great brunch option, especially with a side of Soft Oatmeal Cookies for dessert.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the pie in a preheated oven at 350°F for about 15-20 minutes, or until warmed through. Alternatively, microwave individual slices on medium power for 1-2 minutes.

Frequently Asked Questions

Can I use different types of cheese?

Yes, you can experiment with different cheese varieties. Gouda or Monterey Jack would work well in place of sharp cheddar, providing a different flavor profile. Just be sure to use cheeses that melt well to maintain a creamy texture.

Is it possible to make this pie ahead of time?

Absolutely! You can prepare the pie a day in advance and refrigerate it before baking. Just cover it tightly with plastic wrap. Bake it fresh when you're ready to serve, but add an extra 5-10 minutes to the baking time if it's cold from the fridge.

Can I add other vegetables to this recipe?

Yes, feel free to incorporate other vegetables like sautéed spinach or bell peppers for added flavor and nutrition. Just ensure any additional ingredients are cooked beforehand to avoid excess moisture in the filling.
