Roasted Tomato & Eggplant Boursin Grilled Cheese
Equipment
- Baking sheet
- Parchment paper
- knife
- Cutting board
- Pastry brush or spoon (for olive oil)
- Skillet or nonstick pan
- Spatula
- Oven
- Measuring spoons
Ingredients
Roasted Vegetables
- 1 medium ripe tomato sliced ½-inch thick
- ½ small eggplant sliced ¼-inch thick
- 1½ teaspoons olive oil
- Salt and black pepper to taste
- Optional: pinch of garlic powder or dried oregano
Sandwich
- 2 slices sourdough brioche, or rustic country bread
- 2–3 tbsp garlic & herb Boursin cheese
- 3-4 fresh basil leaves
- 1–2 slices mozzarella or provolone optional, for extra melt
- 1 tablespoon butter softened
Instructions
Roast the Vegetables
- Preheat oven to 425°F (220°C).
- Arrange tomato and eggplant slices on a parchment-lined baking sheet.
- Brush lightly with olive oil; season with salt, pepper, and optional garlic powder or oregano.
- Roast for 20–25 minutes, flipping eggplant halfway, until vegetables are tender and lightly caramelized.
- Let cool slightly to prevent soggy bread.
Assemble the Sandwich
- Butter one side of each slice of bread.
- Spread Boursin on the unbuttered side of one slice.
- Layer roasted eggplant, roasted tomato slices, basil leaves, and optional mozzarella.
- Top with the second slice of bread, buttered side facing out.
Grill
- Heat a skillet over medium-low heat.
- Cook for 3–4 minutes per side, pressing gently, until golden brown and the cheese is fully melted.
Serve
- Rest for 1 minute, slice, and serve warm.
Notes
- Salt the eggplant first if time allows: Lightly salting the slices and letting them rest for 10 minutes helps draw out moisture and improves texture, especially for thicker slices.
- Roast, don’t rush: Properly caramelized vegetables add depth and prevent sogginess—avoid under-roasting.
- Cool before assembling: Let roasted tomatoes and eggplant cool slightly so the bread stays crisp while grilling.
- Low and slow heat: Cook the sandwich over medium-low heat to ensure even browning and fully melted cheese.
- Bread choice matters: Sturdy breads like sourdough or country loaf hold up best to roasted vegetables.
- Optional flavor boost: A drizzle of balsamic glaze, honey, or a pinch of chili flakes elevates the final bite.
- Make it vegan: Use plant-based butter and dairy-free herb cheese for a vegan-friendly version.
FAQ – Roasted Tomato & Eggplant Boursin Grilled Cheese
Can I make this sandwich ahead of time?
You can roast the vegetables up to 2 days in advance and store them in the refrigerator. Assemble and grill the sandwich fresh for best texture.
Do I need to peel the eggplant?
No, peeling isn’t necessary. The skin softens during roasting and helps the slices hold their shape in the sandwich.
What type of Boursin works best?
Garlic & Herb is ideal, but Shallot & Chive or Basil & Chive Boursin also work beautifully.
Can I cook this in a panini press or grill?
Yes. A panini press works very well—just cook until the bread is golden and the cheese is fully melted.
What can I serve with this sandwich?
It pairs well with tomato soup, a simple green salad, or roasted potatoes for a complete meal.
How do I keep the sandwich from falling apart?
Use thin vegetable slices, avoid overfilling, and let the sandwich rest for 1 minute before slicing.
Is this sandwich kid-friendly?
Yes. For kids, you can reduce the herbs or omit basil for a milder flavor.
Can I freeze this sandwich?
Freezing is not recommended, as the roasted vegetables and cheese can become watery when reheated.
