Ingredients List

Here’s what you’ll need to create this delicious creamy French onion casserole:

• 3 large yellow onions, thinly sliced
• 2 tablespoons olive oil
• 1 tablespoon butter
• 2 cloves garlic, minced
• 1 teaspoon fresh thyme, chopped (or ½ teaspoon dried thyme)
• ½ cup dry white wine (optional; can substitute with vegetable broth)
• 2 cups heavy cream
• 1 cup beef broth (or vegetable broth for vegetarian version)
• 1 teaspoon salt
• ½ teaspoon black pepper
• 2 cups croutons or stale bread cubes
• 1 ½ cups Swiss cheese, grated
• ½ cup Parmesan cheese, grated

For those looking to customize, feel free to substitute gluten-free bread for the croutons, or use low-fat cream for a lighter version without compromising flavor.

Timing

The preparation for this creamy French onion casserole takes about 20 minutes, with a cooking time of 40 minutes. This means you’ll be savoring the tantalizing aromas wafting from your oven in just under an hour—a solid 20% less time than average casserole recipes that often take an hour or more!

Step 1: Caramelize the Onions

In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions and a pinch of salt, stirring occasionally. Cook for about 20-25 minutes until the onions are a rich, golden brown. This may seem like a long time, but this step is crucial for developing the deep flavors of your casserole.

Step 2: Add Garlic and Thyme

Once the onions are caramelized, stir in the minced garlic and fresh thyme, cooking for an additional 2-3 minutes until fragrant.

Step 3: Deglaze the Pan

If you’re using white wine, pour it into the skillet to deglaze the pan, scraping up any browned bits from the bottom. Let it simmer for about 2 minutes until slightly reduced. If you’re skipping the wine, you can add vegetable broth instead.

Step 4: Mix in Cream and Broth

Stir in the heavy cream and beef broth, along with the salt and pepper. Bring this mixture to a gentle simmer, allowing it to thicken slightly. Remove from heat.

Step 5: Combine with Croutons

In a large mixing bowl, combine the croutons and half of the grated Swiss cheese. Pour the creamy onion mixture over the top, gently mixing until all the croutons are well coated.

Step 6: Transfer to Baking Dish

Grease a 9×13 inch baking dish and pour in the casserole mixture. Spread it evenly across the dish. Top with the remaining Swiss cheese and the Parmesan cheese for that perfect golden crust.

Step 7: Bake

Bake in a preheated oven at 350°F (175°C) for 30-35 minutes or until the cheese is bubbly and golden brown. This step is especially rewarding, as the aroma of the melting cheese fills your kitchen.

Common Mistakes to Avoid

• Ignoring Measurements: Precision is key in cooking, especially with liquids and seasonings. Use measuring cups to ensure the perfect balance.
