This grilled sandwich transforms a classic favorite into a fresh and satisfying meal by combining creamy ricotta, stretchy mozzarella, and sharp Parmesan cheeses with tangy sun—dried tomatoes and crisp spinach. Toasted buttery sourdough provides a sturdy, flavorful base that crisps perfectly and melts the cheese to gooey perfection. It’s an ideal lunch or easy dinner that offers vibrant tastes and textures without complicated steps.
I first made this sandwich when I wanted something more exciting than my usual grilled cheese. Now it’s a go—to for any time I crave an indulgent but fresh bite, and friends always ask for seconds.
Ingredients
- Sourdough bread: Four slices of sourdough bread offers a sturdy and flavorful base that toasts beautifully
- Sun—dried tomatoes: One quarter cup of sun—dried tomatoes drained and chopped brings a punch of umami and tang
- Fresh spinach: One cup of fresh spinach leaves adds a bright leafy crunch and pop of color
- Ricotta cheese: Half a cup of ricotta cheese gives a lush creamy texture that balances the sharpness of the tomatoes
- Mozzarella cheese: Half a cup of shredded mozzarella cheese provides the perfect melt and stretchy cheesiness
- Parmesan cheese: Two tablespoons of grated Parmesan cheese adds a salty nutty depth to the cheese blend
- Butter: Two tablespoons of butter softened for spreading on bread to create a golden crisp crust
- Selection tips: When selecting sun—dried tomatoes choose ones packed in oil for softness and flavor. Fresh spinach is best when crisp and bright green.
Instructions
- Preheat the Skillet:
- Heat your skillet or griddle over medium heat so it’s ready to toast the bread evenly without burning. Patience here is key for perfect grilling.
- Butter the Bread:
- Spread softened butter evenly on one side of each slice of bread. This helps the bread brown beautifully and adds richness to every bite.
- Prepare the Cheese Mixture:
- In a small bowl combine ricotta mozzarella and Parmesan until thoroughly mixed. This blend creates a creamy texture that melts perfectly.
- Assemble the Sandwich:
- Place two slices of bread buttered side down on the skillet. Spread the cheese mixture evenly over them then layer with chopped sun—dried tomatoes and fresh spinach leaves. Top with the remaining slices of bread buttered side up.
- Cook the Sandwich:
- Let each sandwich cook for three to four minutes on each side. You want the bread golden and crisp and the cheese melted thoroughly. Resist the urge to flip too early to avoid falling apart.
- Serve:
- Remove from skillet and let cool just a bit before cutting in half. This gives the cheese a moment to settle so it doesn’t spill out immediately when sliced.

I adore the nutty hint Parmesan brings to the cheese mixture making every bite richer. Preparing this sandwich always reminds me of cozy afternoons spent experimenting in the kitchen turning simple ingredients into something special.
Storage Tips
If you have leftovers wrap sandwiches tightly in foil or plastic wrap and refrigerate. They reheat best in a skillet over low heat to revive the crispiness without drying out the cheeses. Avoid microwaving if you want to keep that perfect texture.
Ingredient Substitutions
Swap sourdough for a rustic Italian loaf or a hearty whole grain bread if you want a different texture or flavor. You can replace fresh spinach with arugula for a peppery twist or use goat cheese instead of ricotta for a tangy creaminess.
Serving Suggestions
Pair with a simple tomato soup or a crisp salad dressed with lemon vinaigrette to complement the rich sandwich. A light sparkling water or a chilled white wine brightens the meal beautifully.

Enjoy the sandwich warm for the best texture and flavor. It elevates simple ingredients into a satisfying meal.
