Cooking Steps
Halve, peel, and thinly slice onions.
Heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add onions; cook, stirring occasionally, until browned and softened, 8-10 minutes. Stir in 2 tsp sugar, stock concentrates, and ¼ cup water. Cook, stirring, until onions are jammy and water is absorbed, 2-3 minutes more. Remove pan from heat and stir in half the garlic herb butter until melted; season with salt and pepper. Transfer onions to a small bowl. Wipe out pan.
Spread half the sourdough slices with remaining garlic herb butter. Evenly top buttered slices with gouda and onions, then top with remaining slices to make sandwiches.
Heat 1 TBSP butter in a large pan over medium heat. Add sandwiches; cook until bread is golden and cheese melts, 4-6 minutes per side. (Work in batches if necessary).
Cut in half on a diagonal and serve.

Review summary
Updated on Sep 2026- Flavor: The caramelized onion and Gouda combination delivers rich, savory flavor that genuinely tastes like French onion soup in sandwich form. Some found the onions too sweet; skip or reduce the added sugar if you prefer a more savory result.
- Ease of prep: The sandwich itself is quick to assemble, but caramelizing the onions takes more time than expected — plan for at least 15–20 minutes total. Prepping the onions ahead of time makes the final cook much faster.
- Suggestions: Add more cheese — many felt one or two thin slices per sandwich wasn't enough to cover the large sourdough bread. A few reviewers added cheddar, gruyère, or mozzarella from their own fridge to boost the cheesy pull, and some added bacon, apple slices, or stone-ground mustard for extra flavor and texture.
- Leftovers: This sandwich is best enjoyed fresh and hot; one reviewer noted it doesn't reheat as well, so it's ideal for solo diners to make to order.
- Portions: The sandwich is hearty but works better as a lunch than a standalone dinner — pair it with tomato soup or a salad to round out the meal 🍲.
Reviews from our home cooks
This elevated grilled cheese was terrific! The sweet and savory flavors of the onions complimented the richness of the Gouda cheese and garlic herb butter-wow! We paired this with a creamy tomato soup for a warm and comforting weeknight dinner.
Wow! Hands-down, the most gourmet grilled cheese I've ever had! The flavors were a symphony of delicious flavors on my tongue. The Sourdough bread was generously portioned and two pieces of Gouda per sandwich made it perfect. Wouldn't change a thing!
Easy to make & the caramelized onions with Gouda combination was phenomenal!
Flavors are great! One of my onions was a bit small so I think it did not make enough onion jam for 4 sandwiches. The sandwich tasted more like a gouda grilled cheese with an onion condiment. I'll try it again though and have another onion on the side, just in case.
This was incredible! It was fairly easy to prepare and cooked up quickly. It really tasted like French Onion Soup, and the jammy onions really helped to soften up the break to make it a great sandwich. Honestly the best grilled cheese I've had in my life, and I'm so excited there are 4 servings so I will be able to get another meal out of what you sent!
I enjoyed this meal, except that there wasn't enough of the onion mixture for the sandwiches. The bread is large, so the sandwiches are large too. But the onion layer on the sandwiches was skimpy and didn't impart enough of the French onion flavor to the sandwiches.
Omggg amazing! I thought the Gouda and onion might be too much together but they complemented each other perfectly!
I don't even like French onion. But this was very simple and delicious. Saving the recipe for the future. I'll be making it again!
What's not to love? Grilled Cheese Sandwich and French Onion Soup in each delicious bite. A Family Fave.
Easy to make, it was good but could use a little more something for the actual French onion part. But otherwise it was tasty!
