Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Onions: Yellow onions work best for caramelizing due to their natural sweetness.
Butter: Use unsalted butter for better control of flavors.
Beef Broth: Opt for low-sodium broth so you can adjust seasoning later.
Sourdough Bread: Stale sourdough adds texture and flavor; fresh bread gets too soggy.
Gruyère Cheese: This nutty cheese melts beautifully, giving that iconic French onion flavor.
Thyme: Fresh thyme elevates the dish with its aromatic touch.
Salt and Pepper: Essential for balancing flavors; don’t skip these!

Let’s Make it Together
Caramelize those Onions: Begin by melting butter in a large skillet over medium heat. Add thinly sliced onions and cook until they turn golden brown and fragrant, about 15-20 minutes.
Add Broth and Seasoning: Pour in beef broth along with thyme, salt, and pepper. Let this simmer gently until the liquid reduces slightly, about 5-10 minutes.
Prepare Your Casserole Dish: Preheat your oven to 350°F (175°C). Grease a baking dish with cooking spray or extra butter to prevent sticking.
Create Layers of Flavor: Start layering by placing half of the sourdough bread at the bottom of your greased dish. Then pour half of the caramelized onion mixture over it followed by half of the Gruyère cheese.
Repeat and Top with Cheese: Repeat by adding another layer of sourdough bread topped with remaining caramelized onions. Finish off with all remaining Gruyère cheese on top.
Bake Until Golden Brown: Bake in the preheated oven for 25-30 minutes until everything is bubbly and golden brown on top. Let it cool slightly before serving so you don’t burn your tongue on molten cheese!
This french onion casserole is not just a meal; it’s an experience filled with rich flavors and textures that will have everyone asking for your secret recipe. Enjoy every cheesy bite!
