This recipe quickly became a family favorite I first made it on a rainy evening and now everyone asks for it regularly
Ingredients
- Ground beef: half a pound, provides a savory protein base choose lean for less grease
- Marinara sauce: two cups, adds rich tomato flavor and moisture use a high-quality or homemade variety for best taste
- Ricotta cheese: half a cup, gives creaminess and a mild tang look for fresh ricotta that is smooth and not watery
- Parmesan cheese: half a cup grated, delivers a salty, nutty punch freshly grated tastes better than pre-packaged
- Italian seasoning: half a teaspoon, adds classic herb notes fresh dried herbs work well
- Unsalted butter: four tablespoons softened, important for a buttery crisp crust softened butter spreads easier without tearing bread
- Sourdough bread: eight slices, sturdy enough to hold fillings and crisp nicely pick thick, fresh slices
- Mozzarella cheese: one cup shredded, the melty stretchy cheese that makes every bite irresistible use whole milk mozzarella for creamier texture
Instructions
- Cook the Ground Beef:
- In a large skillet over medium heat, cook the ground beef until it is browned and fully cooked, about five to seven minutes. Use a spatula to break the meat into small pieces and stir often for even cooking. Drain excess grease to avoid soggy sandwiches.
- Add Marinara Sauce:
- Lower the heat and stir in one cup of marinara sauce to the cooked beef. Let it simmer gently for two to three minutes so the flavors meld and the mixture is warmed through. Remove from heat and set aside.
- Mix Ricotta Cheese:
- In a medium bowl, combine the ricotta cheese, grated parmesan, and Italian seasoning. Stir thoroughly until the mixture is smooth and evenly seasoned. This will be the creamy layer in the sandwich.
- Prepare the Bread:
- Spread half a tablespoon of softened butter evenly on one side of each slice of sourdough bread. Buttering the bread creates a golden crust when grilled.
- Assemble Sandwiches:
- On the unbuttered side of four slices, spread about two tablespoons of the ricotta mixture. Spoon roughly one-third cup of the beef mixture evenly over the ricotta. Sprinkle a quarter cup of shredded mozzarella on top.
- Top Sandwiches:
- Place the remaining four slices of bread on top with the buttered side facing outward, creating four sandwiches.
- Cook Sandwiches:
- Heat a large skillet over medium heat. Cook one or two sandwiches at a time, placing them carefully in the skillet. Grill each side for three to four minutes until the bread is golden brown and crispy and the cheese inside has melted completely.
- Serve:
- Serve immediately with the remaining marinara sauce for dipping. This adds a lovely tangy contrast to the rich sandwich.

Mozzarella is my personal favorite ingredient here because it melts beautifully, giving that iconic gooey pull with every bite. A fun family memory is how my kids try to stretch the cheese as far as possible before taking their first bite; it adds a little playful competition to dinner.
Storage Tips
Store leftover sandwiches in an airtight container in the refrigerator for up to three days. Allow them to cool completely before sealing to maintain crispness.
Ingredient Substitutions
Try ground turkey or plant-based meat alternatives to lighten the dish or cater to dietary preferences. Swap ricotta with cream cheese for an even creamier texture or experiment with provolone or gouda cheese for different flavor profiles.
Serving Suggestions
Pair with a crisp Caesar or Caprese salad to balance richness. Extra marinara sauce is excellent for dipping. Adding crunchy snacks like potato chips or pickles brings texture variety and completes the meal beautifully.

Enjoy hot with extra marinara for dipping. It’s comfort food made easy.
