Step 1: Make the Gnocchi
Cook the Potatoes:
Boil the potatoes in salted water until fork-tender, about 20-25 minutes. Drain and let them cool slightly.
Prepare the Dough:
Peel the warm potatoes and mash them until smooth using a potato masher. Transfer the mashed potatoes to a clean work surface. Make a well in the center, add the egg (if using), and sprinkle salt. Gradually add flour, mixing until a soft dough forms. You may not need all the flour, so add it gradually.
Knead the Dough:
Gently knead the dough for about 2-3 minutes until it’s smooth but not sticky. Be careful not to overwork it.
Shape the Gnocchi:
Divide the dough into four portions. Roll each portion into a long rope, about ¾ inch thick. Cut the rope into 1-inch pieces. If desired, use a fork to create ridges on each piece for better sauce adherence.
Step 2: Prepare the Sauce
Cook the Sauce:
In a skillet, heat olive oil over medium heat. Add the minced garlic and sauté for about 30 seconds, or until fragrant. Add the crushed tomatoes, salt, and pepper. Simmer for about 10-15 minutes, stirring occasionally, until the sauce thickens.
Step 3: Cook the Gnocchi
Boil the Gnocchi:
Bring a large pot of salted water to a boil. Add the gnocchi in batches. They are done when they float to the surface, usually in about 2-3 minutes. Use a slotted spoon to transfer them to a baking dish.
Step 4: Combine and Bake
Combine:
Pour the sauce over the gnocchi in the baking dish. Toss gently to combine. Sprinkle mozzarella cheese on top.
Bake:
Preheat your oven to 400°F (200°C). Bake for 15-20 minutes or until the cheese is bubbly and golden.
Step 5: Serve
Serve:
Remove from the oven and let it stand for about 5 minutes. Garnish with fresh basil and a sprinkle of Parmesan cheese, if desired.
Variations and Tips
Vegetarian Version: Skip the egg for a lighter gnocchi, or add sautéed vegetables like spinach or mushrooms to the sauce for extra flavor.
Dairy-Free Option: Use plant-based mozzarella and leave out the Parmesan.
Gluten-Free Option: Substitute all-purpose flour with a gluten-free flour blend.
