Ingredients

Why this recipe works

The slow cooking method allows the ground beef to release its juices slowly, which in turn flavors the marinara sauce as it simmers. Because the lid remains closed throughout the duration of the cook, the moisture is trapped inside, creating an environment where the ingredients can soften and meld together without the need for constant stirring or checking.

Cooking in a slow cooker provides a gentle, consistent heat source that is difficult to replicate with other methods. This steady temperature ensures the meat cooks through evenly while the onions become perfectly tender.

The result is a cohesive dish where the savory notes of the seasoning and the acidity of the tomatoes balance each other perfectly, providing a deep, complex flavor profile.

Notes and substitutions

When selecting ground beef, look for a standard lean-to-fat ratio, such as 80/20 or 85/15. This amount of fat is necessary to provide moisture and richness to the sauce as it simmers over the course of the four-hour cooking time. Using ground meat that is too lean may result in a drier texture, while a slightly higher fat content adds great body to the finished dish.

The choice of slow cooker is important; a 6-quart oval model is ideal for ensuring the ingredients are spread out enough to cook evenly. If you have a different size, adjust the cooking time accordingly.

Always ensure the lid fits tightly to keep the heat inside. A standard glass measuring cup is useful for pouring the sauce evenly across the surface of the beef and onions.
