  1. 1

    Preheat the oven to 350 degrees F (180 degrees C). Arrange the meatballs on a baking tray.

  2. 2

    Bake the meatballs in the preheated oven until a slight crust forms, about 15 minutes (they will not be fully cooked). Cover and set aside to keep warm.

  3. 3

    Meanwhile, bring a large pot of salted water to a boil and add the spaghetti. Cook for about 10 minutes, or 1 minute less than the package directions for slightly firm pasta, then drain thoroughly.

  4. 4

    In a large casserole dish, pour about 1/2 cup of the pasta sauce along the bottom and spread to coat. Add the spaghetti evenly over the sauce to cover the entire bottom of the dish.

  5. 5

    Arrange the meatballs in rows over the spaghetti, about 3 in each row for a total of 6 rows. Cover the meatballs and spaghetti evenly with the remaining sauce. Sprinkle with 1/2 cup mozzarella; cover the dish with foil.

  6. 6

    Bake in the preheated oven for 20 minutes, then remove the foil. Sprinkle with the remaining cheese.

  7. 7

    Return to the oven and bake until the cheese is melted, about 15 minutes more. Remove from the oven and let cool for 5 minutes before serving.

How easyChef Pro scores recipes and products

easyChef Pro analyzes up to 41 nutrients using data sourced from USDA and other verified food databases. Its scoring method uses the nutrients relevant to nutrition quality, calorie density, processing level, and your selected health goal. Recipes and food products get a health score from 0 to 100, calculated using consistent rules instead of being estimated by AI. The same nutrition data, serving size and health goal will produce the same result.

The calculation evaluates nutrients, calorie density, processing level, and how well the food supports your selected health goal. Protein, fiber, vitamins, minerals and other beneficial nutrients can strengthen the score. High amounts of sodium, saturated fat, added sugar and other nutrients may lower it.

Your health goal also matters. easyChef Pro evaluates recipes and products across six health areas and adjusts their importance for your selected goal. This means the same food may be a better fit for one health goal than another.

For recipes, changing an ingredient, quantity or serving size changes the nutrition and may change the score. Remix the recipe in easyChef Pro to calculate fresh nutrition and scores for the version you actually make. Product scores are based on the nutrition and serving information associated with that specific product.
