1 tablespoon olive oil
2 medium onions, thinly sliced
1/2 teaspoon dried thyme
1/2 teaspoon dried rosemary, crushed
1 bay leaf

1/2 teaspoon pepper

Caramelizing the Onions

Step 1: Begin extract the Caramelization Process

We’ll start by building the foundation of flavor for our French Onion Grilled Cheese: the deeply caramelized onions. In a large skillet or Dutch oven, heat the 1 tablespoon of olive oil over medium heat. Once the oil is shimmering, add your thinly sliced onions. Stir them well to coat them in the oil. You’ll want to cook these down slowly, stirring occasionally, for about 10-15 minutes untilgin extractey begin to soften and turn translucent. This initial softening is crucial for even caramelization later on. Don’t rush this step; patience here will yield a much richer flavor.

Step 2: Deepen the Flavor and Add Aromatics

Now, it’s time to add tgin extractbutter and begin the true caramelization. Reduce the heat to medium-low. Add 3 tablespoons of the softened butter to the skillet with the onions. Stir to combine. Continue to cook, stirring more frequently now, for another 30-40 minutes, or until the onions are a deep golden brown and wonderfully sweet. As the onions cook, they will release thegin extractnatural sugars and begin to caramelize. During this stage, add the dried thyme, crushed dried rosemary, and the bay leaf. Stir them in and let their fragrant aromas infuse into the onions for the last 10 minutes of cooking. This slow, low heat is key to achieving that beautiful, rich brown color and intense sweetness characteristic of French onion soup.

Step 3: Sweeten and Enhance the Onion Mixture

Once the onions have reached their desired deep golden-brown color and have a jammy consistency, it’s time to add the brown sugar and pepper. Stir in the 1 teaspoon of packed brown sugar and the 1/2 teaspoon of pepper. The brown sugar will help to further enhance the natural sweetness of the onions and contribute to their beautiful caramelization. Continue to cook and stir for another 5 minutes, allowing the sugar to dissolve and meld with the onion flavors. This simple addition elevates the depth of sweetness.

Step 4: Create the Savory Au Jus Infusion

To bring in that classic French onion soup essence, we’ll create a quick au jus. In a small bowl, whisk together the 1/4 cup of water and the 1 ounce of au jus gravy mix until dissolved. Once the onions are deeply caramelized and fragrant, remove and discard the bay leaf. Pour the au jus mixture into the skillet with the onions. Stir well to combine everything. Let this simmer gently for about 5-10 minutes, uncovered, allowing the liquid to reduce slightly and the flavors to concentrate. This process will create a rich, savory, and slightly thickened onion mixture that is perfect for our grilled cheese. Stir in the 3 tablespoons of grated Parmesan cheese at the very end, allowing it to melt into the mixture for added savoriness and a hint of nuttiness. Set this flavorful onion mixture aside.

Assembling and Grilling the French Onion Grilled Cheese

Step 5: Assemble Your Masterpiece

Now that our deeply flavorful caramelized onion mixture is ready, it’s time to build the ultimate French Onion Grilled Cheese. Lay out your 8 slices of sourdough bread. Spread the remaining 2 tablespoons of softened butter evenly on one side of each slice of bread. This buttered side will be the outside of your sandwich, ensuring a perfectly golden and crispy exterior. On the unbuttered side of four of the bread slices, layer 2 slices of Swiss cheese each. Generously spoon a good amount of the caramelized onion mixture over the Swiss cheese on these four slices. Top the onion mixture with a healthy portion of the shredded Gruyere cheese. Finally, place the remaining four slices of sourdough bread on top, butter-side up, to complete the sandwiches. Ensure the cheese and onion mixture is relatively contained within the bread to avoid excessive oozing during grilling.

Step 6: Grill to Golden Perfection

Heat a large skillet or griddle over medium heat. Once the skillet is hot, carefully place two or three assembled sandwiches onto the hot surface, being mindful not to overcrowd the pan. Grill for approximately 4-5 minutes per side, or until the bread is a beautiful golden brown and the cheese is completely melted and gooey. You’ll want to watch these closely to prevent burning. The medium heat allows the bread to toast to a perfect crisp while giving the cheese ample time to melt. If the bread is browning too quickly, you can reduce the heat slightly. If the cheese isn’t melting sufficiently, you can briefly cover the skillet to trap steam and encourage melting. Once grilled to perfection on both sides, remove the sandwiches from the skillet. Repeat this process with any remaining sandwiches. Serve immediately for the ultimate, decadent French Onion Grilled Cheese experience.
