Essential Ingredients

Here’s what you’ll need to make this delicious dish:

  • Unsalted Butter: Choose high-quality butter to enhance flavor; it also helps in achieving that lovely golden color.

  • Fresh Cornbread: You can use store-bought or homemade; either way, ensure it’s slightly stale for best texture.

  • Heavy Cream: This creamy goodness gives the gratin its richness; go for fresh cream whenever possible.

  • Grated Cheese (Cheddar or Gruyère): A blend of cheeses adds depth; opt for sharp cheddar for a more pronounced flavor.

  • Fresh Thyme: A sprinkle of thyme brightens everything up; use fresh if you can find it!

  • Salt and Pepper: Essential seasonings to enhance all those scrumptious flavors throughout the dish.

How to Make Caramelized Onion & Cornbread Gratin

Caramelize the Onions: Melt butter in a large skillet over medium heat. Add sliced onions and stir occasionally until they are golden brown and fragrant, about 20-30 minutes.

Prepare the Cornbread Base: Cut your cornbread into cubes while the onions are caramelizing. Ensure they’re slightly stale to absorb all that creamy goodness without turning mushy.

Mix the Cream and Cheese: In a bowl, combine heavy cream with half of your grated cheese. Season with salt, pepper, and thyme for added flavor depth.

Assemble the Gratin: Layer half of the cornbread cubes in a greased baking dish. Top with half of the caramelized onions followed by half of the cheese mixture. Repeat layering all components until used up.

Bake to Perfection: Preheat your oven to 350°F (175°C). Bake for 30-35 minutes until bubbly and golden on top. Let cool slightly before serving—this helps set those layers beautifully.

This Caramelized Onion & Cornbread Gratin is more than just comfort food; it’s an invitation to gather around the table and share stories over delicious bites. Whether it’s an intimate dinner or a bustling holiday celebration, this dish promises smiles all around!
