- 2 tablespoons unsalted butter

How to Prepare *French Onion Casserole*
Now, let’s dive into the delicious journey of making my French onion casserole! It’s easier than you might think, and each step brings you closer to that gooey, cheesy goodness. Ready? Let’s go!
Step 1: Caramelize the Onions
First things first, grab a large skillet and melt the butter along with the olive oil over medium heat. You want that butter to be nice and bubbly, but not burnt! Now, toss in your sliced onions, sprinkle with salt and pepper, and give them a good stir. Let them cook for about 25 minutes, stirring occasionally. You’re aiming for that beautiful golden-brown color and a sweet, caramelized flavor. Trust me, this step is magic!
Step 2: Create the Flavor Base
Once those onions are perfectly caramelized, it’s time to elevate the flavors! Add in the fresh thyme and pour in the beef broth. Give it a gentle stir and let it simmer for about 10 minutes. This is when all those lovely flavors meld together, creating a rich base that will make your casserole shine. Make sure to taste it—yum!
Step 3: Assemble the Casserole
Now comes the fun part—layering! Preheat your oven to 350°F (175°C). In a baking dish, start with a layer of that glorious onion mixture, followed by a drizzle of heavy cream. Then, sprinkle a generous amount of grated Gruyère cheese over the top, followed by a layer of breadcrumbs for that perfect crunchy topping. Make sure to spread everything evenly so each bite has a delightful mix of flavors!
Step 4: Bake the Casserole
Pop your assembled casserole into the oven and let it bake for about 30 minutes. You’ll know it’s ready when the top is golden brown and bubbly—oh, the aroma is heavenly! Just let it cool for a few minutes before serving. I promise, the wait will be worth it as you scoop out that cheesy, oniony goodness!
Tips for Success
To ensure your French onion casserole turns out perfectly, here are a few handy tips! First, don’t rush the caramelization—allow those onions to cook low and slow for that rich, sweet flavor. Stir them occasionally, but let them do their thing! When it comes to cheese, Gruyère is a classic choice for its meltiness, but feel free to mix it up with Swiss or even a sharp cheddar for a bolder taste. And remember, letting the casserole cool for a few minutes after baking helps it set, making for easier serving. Trust me, these little details make a big difference!

FAQ Section
Can I use a different cheese?
Absolutely! While Gruyère is my go-to for that rich, nutty flavor, you can definitely switch it up. Swiss cheese is a great alternative—it melts beautifully and has a mild taste. If you’re feeling adventurous, try a sharp cheddar for a bolder kick! Just keep in mind that different cheeses can slightly alter the flavor profile, but they’ll still deliver that deliciously gooey texture we love.
How do I store leftovers?
Storing leftovers is super easy! Just let your French onion casserole cool completely, then transfer it to an airtight container. It’ll keep in the fridge for about 3-4 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through. You can also microwave it, but I find the oven keeps that lovely crispy topping intact. Yum!
Can I make this dish ahead of time?
Yes, you can totally prep this dish ahead of time! Just assemble the casserole as directed, cover it tightly with foil, and store it in the fridge for up to 24 hours before baking. When you’re ready to serve, pop it in the oven straight from the fridge—just add a few extra minutes to the baking time to ensure it’s heated through. It’s a lifesaver for busy nights or special occasions!
Serving Suggestions
Now that you’ve got your delicious French onion casserole ready to go, let’s talk about what to serve alongside it! I love pairing this cozy dish with a simple green salad dressed in a light vinaigrette to balance the richness of the casserole. A crusty baguette or some warm, toasted garlic bread is perfect for soaking up all that cheesy goodness, too! And if you’re in the mood for a little something extra, a glass of full-bodied red wine pairs beautifully with the savory flavors. Trust me, this combination will make your meal feel like a true French feast!
