How to Cook Onions for Casseroles

If you’re wondering should you cook onions before putting them in casserole, here are some simple techniques:

1. Sautéing

Sautéing is the most common method:

  • Heat oil or butter in a skillet over medium heat.
  • Add chopped onions and cook until translucent or lightly golden.
  • Season lightly with salt to draw out their natural sweetness.

2. Caramelizing

For richer, deeper flavors:

  • Cook onions over low heat for 15-20 minutes.
  • Stir occasionally to prevent sticking or burning.
  • Add a splash of broth or water if necessary.

3. Microwave Par-Cooking

For a quick solution:

  • Place diced onions in a microwave-safe bowl with a drizzle of oil.
  • Microwave on high for 2-3 minutes, stirring halfway.

When You Can Skip Cooking Onions

In some cases, skipping the pre-cooking step might be acceptable:

  • Thinly sliced onions can cook adequately in casseroles baked for long periods.
  • Recipes that aim for a sharp, fresh onion flavor may benefit from using raw onions.

If you choose to skip cooking:

  • Ensure the onions are sliced thinly and evenly for consistent cooking.
  • Combine them with high-moisture ingredients to soften them during baking.

Using Frozen Onions in Casseroles

Frozen onions are a convenient alternative, but they require proper preparation:

  • Thaw them under cold water in a colander.
  • Press out excess moisture with a paper towel to avoid sogginess.
  • Sauté them briefly to enhance their flavor and texture.
