A Look Inside – Nutritional Benefits of Our Slow Cooker Veggie Lasagna 

Let’s take a closer look at the nutritional value of each component:

  1. Olive Oil: The recipe calls for 2 tablespoons of olive oil, which is a healthier alternative to other cooking oils. Olive oil is rich in monounsaturated fats, which have been linked to a reduced risk of heart disease. It also contains antioxidants that have anti-inflammatory properties and may help protect against chronic diseases.
  2. Mushrooms: The recipe includes a pint of chopped mushrooms, which are a low-calorie and nutrient-dense ingredient. Mushrooms are a great source of vitamins and minerals, including B vitamins, copper, and selenium. They are also a natural source of antioxidants and dietary fiber, which can support a healthy digestive system.
  3. Green Bell Pepper: Green bell peppers add a vibrant color and refreshing flavor to the lasagna. They are packed with vitamins A, C, and K, as well as dietary fiber. Bell peppers also contain antioxidants that may help protect against cellular damage and support overall health.
  4. Sweet Onion: The addition of a large sweet onion not only enhances the flavor of the lasagna but also provides important nutrients. Onions are a good source of vitamin C, vitamin B6, and dietary fiber. They also contain compounds that have been associated with various health benefits, such as reducing inflammation and supporting heart health.
  5. Baby Spinach: The recipe incorporates 3 cups of chopped baby spinach, which is a leafy green vegetable known for its nutritional value. Spinach is low in calories but rich in vitamins A, C, and K, as well as folate, iron, and calcium. It is also a good source of antioxidants, which can help combat oxidative stress in the body.
  6. Cottage Cheese: The recipe includes 1 pound of 2% cottage cheese, which adds creaminess and protein to the lasagna. Cottage cheese is a great source of protein, calcium, and phosphorus. It is also lower in fat compared to other cheese varieties, making it a healthier choice.
  7. Mozzarella Cheese: The lasagna is layered with shredded mozzarella cheese, providing a gooey and satisfying texture. Mozzarella cheese is a good source of calcium and protein. It also contains essential nutrients like phosphorus and vitamin B12.
  8. Salt: While the recipe calls for a small amount of salt (1/4 teaspoon), it helps enhance the flavors of the dish. It’s important to note that excessive sodium intake should be avoided, so it’s best to use salt in moderation.
  9. Low-Sodium Pasta Sauce: The lasagna is enriched with a 26 oz. jar of low-sodium pasta sauce. This choice reduces the overall sodium content of the dish. The specific nutritional profile may vary depending on the brand and ingredients used in the sauce.
  10. Zucchini: Sliced zucchini adds a touch of freshness and nutritional benefits to the lasagna. Zucchini is low in calories and a good source of dietary fiber, vitamins A and C, and minerals like potassium. It also adds a delightful texture to the dish.
  11. Whole Wheat Lasagna Noodles: The recipe calls for 8 ounces of no-boil whole wheat lasagna noodles. Whole wheat noodles provide more fiber and nutrients compared to refined wheat noodles. They are a good source of complex carbohydrates and can help regulate blood sugar levels.
