Grilled Cheese with Gouda, Roasted Mushrooms and Onions Recipe
Introduction
This grilled cheese sandwich takes a delicious twist with creamy Gouda cheese and the rich flavors of roasted mushrooms and sweet onions. It’s a comforting, savory treat perfect for any time you crave a warm, satisfying meal.

Ingredients
- 8 ounces of sliced mushrooms
- 1 medium sweet onion, sliced
- 2 tablespoons of olive oil
- Salt and pepper, to taste
- 4 tablespoons of butter
- 4 slices of your favorite bread
- 1 cup of shredded Gouda cheese
Instructions
- Step 1: Preheat your oven to 400°F (200°C). Slice mushrooms into 1/4-inch pieces and thinly slice the sweet onion. Toss mushrooms and onions with olive oil, salt, and pepper. Spread evenly on a baking sheet, making sure pieces aren’t crowded, then roast until golden brown.
- Step 2: While the vegetables roast, shred the Gouda cheese using a grater to ensure even melting.
- Step 3: Prepare your bread by slicing it to a thickness that can hold the fillings without becoming soggy.
- Step 4: Melt butter in a skillet over medium heat. Brush one side of each bread slice with melted butter to help create a golden crust.
- Step 5: Assemble the sandwich by layering shredded Gouda on the unbuttered side of one bread slice, add roasted mushrooms and onions, then more Gouda. Top with another bread slice, buttered side facing out.
- Step 6: Place the sandwich in the skillet. Cook each side for 3 to 4 minutes until the bread is golden brown and the cheese is melted. Press lightly with a spatula to crisp the bread evenly.
- Step 7: Remove from heat and cut the sandwich in half. Serve immediately to enjoy the warm, gooey cheese and savory roasted vegetables.
Tips & Variations
- Substitute sweet onion with red onion for a sharper flavor.
- Use sourdough or rye bread for added texture and taste.
- Add fresh herbs like thyme or rosemary to the mushrooms before roasting to elevate the flavor.
- For a vegan version, use plant-based butter and cheese substitutes.
Storage
Store leftover sandwiches in an airtight container in the refrigerator for up to 2 days. To reheat, warm in a skillet over low heat to maintain crispness or use a toaster oven. Avoid microwaving as it can make the bread soggy.

FAQs
Can I use other types of cheese instead of Gouda?
Yes, cheeses that melt well like cheddar, Monterey Jack, or fontina work great as substitutes while still delivering a creamy texture.
How do I prevent the sandwich from getting soggy?
Make sure to toast the bread butter-side down in the skillet and avoid overloading the sandwich with too many moist ingredients. Slicing the bread thickly also helps keep it crisp.

Ingredients
Vegetables
- 8 ounces sliced mushrooms (about 1/4-inch thickness)
- 1 medium sweet onion, thinly sliced
- 2 tablespoons olive oil
- Salt and freshly cracked pepper, to taste
Sandwich
- 4 tablespoons unsalted butter
- 4 slices of your favorite bread, thickly sliced
- 1 cup shredded Gouda cheese
Instructions
- Roast the vegetables: Preheat the oven to 400°F (200°C). Toss the sliced mushrooms and onions in olive oil, ensuring each piece is well coated. Season with salt and pepper. Spread them evenly on a baking sheet, leaving space between pieces to prevent steaming, then roast until golden brown and caramelized, about 15-20 minutes.
- Prepare the cheese: While the vegetables roast, shred the Gouda cheese using a cheese grater to ensure it melts evenly and achieves a creamy texture.
- Prepare the bread: Choose your favorite thick-sliced bread, which will hold the fillings well without becoming soggy, providing a pleasant crunch.
- Butter the bread: Melt the unsalted butter in a skillet over medium heat. Brush one side of each bread slice with melted butter to help create a golden, crispy crust during grilling.
- Assemble the sandwich: On the unbuttered side of a bread slice, layer shredded Gouda cheese, then add a generous amount of the roasted mushrooms and onions. Top with more shredded Gouda, then place another slice of bread on top, buttered side facing out.
- Grill the sandwich: Place the assembled sandwich in the skillet. Cook for 3 to 4 minutes on each side, pressing gently with a spatula to enhance crispiness, until the bread is golden brown and the cheese is melted thoroughly.
- Serve: Remove the sandwich from the skillet and cut in half for easy handling. Serve immediately to enjoy the warm, melty cheese combined with the savory roasted vegetables and crisp bread.
Notes
- Make sure to spread the mushrooms and onions in a single layer when roasting to avoid steaming and to get a nice caramelization.
- Using shredded Gouda cheese instead of pre-sliced allows for better melting and creamier texture.
- Butter the bread generously to ensure an even, golden crust when grilling.
- Serve immediately for the best texture and taste, as the sandwich can become soggy if it sits too long.
- You can add a pinch of fresh thyme or rosemary to the vegetables before roasting for an herbal twist.
