Ingredients
- 4 slices sourdough bread
- 2 tablespoons unsalted butter
- 1 medium pear, thinly sliced
- 1 medium apple, thinly sliced
- 1 medium onion, thinly sliced
- 1 cup shredded sharp cheddar cheese
- 1 tablespoon balsamic vinegar
- Salt to taste
- Black pepper to taste
Instructions
- Step 1: Caramelize the onions by melting 1 tablespoon of unsalted butter in a skillet over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for about 10 minutes until golden brown and softened. Stir in the balsamic vinegar and cook for another 2-3 minutes. Remove the onions from the skillet and set aside.
- Step 2: In the same skillet, melt the remaining tablespoon of butter over medium heat. While it melts, assemble the sandwiches by layering half the cheddar cheese on two slices of sourdough bread. Add the caramelized onions, then evenly distribute the apple and pear slices. Top with the remaining cheddar cheese and cover with the other two slices of bread.
- Step 3: Place one sandwich in the skillet and grill for 4-5 minutes on one side until golden brown. Carefully flip and grill the other side for another 4-5 minutes, allowing the cheese to melt thoroughly.
- Step 4: Repeat the grilling process with the second sandwich. Once done, remove both sandwiches from the skillet, let them cool for a minute, then slice in half and serve warm.
Tips & Variations
- For extra flavor, add a sprinkle of fresh thyme or rosemary to the caramelized onions while cooking.
- Swap sharp cheddar for Gruyère or fontina for a different cheese profile.
- Try using multigrain or rye bread for a heartier texture.
- To make it vegetarian-friendly, ensure the bread and butter are free of animal products or substitute with plant-based alternatives.
Storage
Store leftover sandwiches in an airtight container in the refrigerator for up to 2 days. To reheat, warm gently in a skillet over low heat or in a toaster oven until the cheese is melted and the bread is crisp again. Avoid using a microwave to keep the bread from becoming soggy.

Ingredients
Bread & Butter
- 4 slices sourdough bread
- 2 tablespoons unsalted butter
Fruit & Vegetables
- 1 medium pear, thinly sliced
- 1 medium apple, thinly sliced
- 1 medium onion, thinly sliced
Dairy
- 1 cup shredded sharp cheddar cheese
Additional
- 1 tablespoon balsamic vinegar
- Salt to taste
- Black pepper to taste
Instructions
- Caramelize the onions: In a skillet over medium heat, melt 1 tablespoon of unsalted butter. Add the thinly sliced onions along with a pinch of salt. Cook them while stirring occasionally for about 10 minutes, until the onions turn golden brown and softened. Add 1 tablespoon of balsamic vinegar and cook for an additional 2 to 3 minutes to intensify the flavor. Remove the caramelized onions from the skillet and set them aside.
- Prepare the skillet: In the same skillet, melt the remaining tablespoon of unsalted butter over medium heat in preparation for grilling the sandwich.
- Assemble the sandwiches: Lay out two slices of sourdough bread. On each slice, evenly distribute half of the shredded cheddar cheese. Next, layer on the caramelized onions, then the thinly sliced apple followed by the pear slices. Top each sandwich with the remaining cheddar cheese and cover with the other two slices of bread.
- Grill the sandwiches: Place one assembled sandwich in the preheated skillet. Grill on one side for 4 to 5 minutes, or until the bread is golden brown and crisp. Carefully flip the sandwich using a spatula and grill the other side for another 4 to 5 minutes, ensuring the cheddar cheese melts thoroughly and the sandwich heats through.
- Finish and serve: Repeat the grilling process for the second sandwich. Once cooked, remove both sandwiches from the skillet. Let them rest and cool for a minute, then slice in half and serve warm for the best flavor and texture experience.
Notes
- Use ripe but firm pears and apples to prevent the sandwich from getting soggy.
- Sharp cheddar cheese adds a nice tang, but feel free to experiment with other melting cheeses like Gruyère or fontina.
- For extra flavor, sprinkle a little black pepper over the fruit layers before closing the sandwich.
- To speed up caramelizing, slice the onions very thinly.
- Cook over medium heat to ensure bread crisps without burning before cheese melts.
