Recipe FAQs

Can I use a different type of bread?

Yes, thick-cut white bread, ciabatta, or focaccia work well. The key is choosing bread sturdy enough to hold the cheese and pesto without falling apart during cooking.

How do I prevent the bread from burning while the cheese melts?

Cook on medium heat rather than high, and press gently with a spatula. You can also lower the heat to medium-low and cover the skillet briefly to trap steam, which helps the cheese melt faster.

What if I don't have fontina cheese?

Fontina is interchangeable with gruyère, provolone, or gouda. Use any melting cheese you prefer—the blend creates richness, but any single cheese works fine.

Is homemade pesto better than store-bought?

Both work beautifully. Homemade pesto offers fresher basil flavor, but store-bought saves time. If making homemade, blend fresh basil, garlic, pine nuts, parmesan, and olive oil to your preferred consistency.

Can I make this vegan?

Absolutely. Substitute plant-based butter, dairy-free cheese alternatives, and ensure your pesto is vegan or make it without cheese. The cooking method remains the same.

What sides pair well with this sandwich?

Tomato soup is classic. Alternatively, serve with a crisp green salad, roasted vegetables, or pickles for a light, balanced meal.
