Tips for success
For a deeper flavor profile, consider browning the Italian sausage in a skillet before adding it to the slow cooker. While this adds a small amount of prep time, the caramelized exterior of the meat adds a wonderful depth to the final marinara sauce. Simply drain any excess fat before layering the sausage into the slow cooker, then proceed with the recipe as directed.
If you prefer a more vibrant presentation, add the zucchini during the final hour of cooking instead of at the beginning. This will result in a firmer texture for the zucchini, which some prefer.
However, keep in mind that the zucchini will absorb less of the sauce's flavor when cooked for a shorter period, so balance this preference against your desire for a more integrated flavor.
Variations
- Vegetable Medley: Add sliced bell peppers and onions along with the zucchini for a more colorful and textured dish that adds a slight sweetness to the overall flavor profile.
- Spicy Kick: Incorporate a teaspoon of crushed red pepper flakes along with the Italian seasoning to give the marinara sauce a noticeable heat that pairs well with the savory sausage.
Storage and make-ahead
- Fridge
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Freezer
- Freeze in a freezer-safe bag or container for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheat
- Reheat in a saucepan over medium heat until steaming, or microwave in 1-minute intervals until thoroughly heated.
Allow any leftovers to cool to room temperature for no longer than two hours before transferring them to an airtight container. Storing the food promptly helps maintain its quality and safety.
Place the container in the coldest part of your refrigerator, where it will remain fresh for up to three days. When ready to eat again, ensure the meal is heated thoroughly before serving to maintain the best flavor and texture.
This dish is excellent for make-ahead meal preparation. You can assemble the raw ingredients in the slow cooker insert, cover it, and keep it in the refrigerator overnight. When you are ready to cook, simply place the insert into the slow cooker base and start the cooking process. This is a convenient way to have a hot dinner ready with almost zero effort after a long day.
Serving ideas
Serve this dish in shallow bowls to showcase the beautiful colors of the marinara and zucchini. A sprinkle of fresh mozzarella cheese over the hot stew creates a lovely melted finish that adds a creamy element to the meal.
You might also consider serving it alongside a slice of crusty bread to soak up the flavorful sauce, which many find to be the best part of the experience.
For a more substantial meal, this marinara can be served over your favorite pasta, such as penne or rigatoni, which holds the sauce well. The simplicity of the dish allows it to pair easily with various sides, making it a versatile option for casual dinners.
Remember to allow the dish to rest for five minutes after cooking, which helps the flavors settle and makes the sauce easier to spoon over your chosen base.

- 2 cups zucchini, sliced into half-moons
- 1 packet Italian seasoning
- 24 oz marinara sauce
- 1/2 cup shredded mozzarella cheese, optional for serving
Instructions
- Place the sliced Italian sausage at the bottom of the slow cooker basin. Arrange the zucchini half-moons evenly over the sausage layer to ensure they cook through properly during the long simmering process.
- Sprinkle the Italian seasoning packet over the layered zucchini and sausage. Pour the marinara sauce over the top, ensuring that all ingredients are well covered to prevent any parts from drying out during the cooking time.
- Cover the slow cooker and cook on low for 4 hours. Once the time is up, ensure the sausage has reached an internal temperature of 160°F (71°C). Serve immediately with a sprinkle of mozzarella cheese if desired, allowing the dish to rest for 5 minutes before portioning.
