Preheat your oven to 375°F (190°C).

In a large skillet, heat olive oil over medium heat. Add minced garlic and sauté for about 1 minute.

Add the cooked shrimp to the skillet and stir gently, cooking for 2-3 minutes.

In a bowl, combine the sautéed shrimp with ricotta cheese, half of the mozzarella cheese, Parmesan cheese, thawed spinach, and Italian seasoning.

Lay a flour tortilla flat, spoon the filling into the center, and roll it tightly.

Pour Alfredo sauce into the bottom of a baking dish, arrange roll-ups seam-side down.

Pour remaining Alfredo sauce over the top of the roll-ups.

Sprinkle remaining mozzarella cheese on top.

Cover with aluminum foil and bake for 20 minutes, uncover and bake for an additional 10-15 minutes.

Let cool for about 5 minutes, then garnish with chopped parsley before serving.
