Slow Cooker French Onion Gravy Turkey Breast Tips, FAQ & printable recipe

Tips for success

For a deeper onion flavor, you can sauté the sliced onions in a little butter on the stovetop before placing them in the slow cooker, though this is optional.

This extra step adds a layer of caramelization that complements the savory gravy perfectly.

Consider serving this dish with a side of mashed potatoes or steamed green beans to soak up the excess onion gravy.

The sauce is the highlight of the meal, so ensure you have plenty of it to spoon over the sliced turkey and your chosen side dishes.

Variations

• Mushroom Onion Turkey: Add 1 cup of sliced cremini mushrooms to the slow cooker along with the onions. The mushrooms add an earthy depth that pairs exceptionally well with the onion gravy and tender turkey meat.
• Herbed Turkey Breast: Add 1 tablespoon of fresh thyme or rosemary leaves to the slow cooker when adding the onions. The herbs provide a fresh, aromatic contrast to the savory onion soup mix and gravy.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days.

Freezer

Freeze in a freezer-safe container for up to 2 months.

Reheat

Reheat gently on the stovetop over low heat or in the microwave until warmed through.

Allow any leftovers to cool to room temperature for no more than two hours. Once cooled, place the turkey and gravy into an airtight container.

Keep the meat submerged in the gravy to maintain moisture during storage. It will keep well in the refrigerator for up to three days.

You can prepare the ingredients and layer them in the slow cooker insert the night before, then keep the insert in the refrigerator.

In the morning, simply place the insert into the slow cooker base and start the cooking cycle to save time during the day.

Serving ideas

Serve the turkey breast sliced thinly on a warm platter, topped with the cooked onions and a generous amount of the thickened gravy. This presentation is elegant enough for a family dinner yet simple enough for a regular weeknight meal.

Pair this dish with rustic bread or roasted root vegetables to create a balanced, hearty meal. The rich, savory gravy works beautifully with mild side dishes that allow the flavor of the onion-infused turkey to stand out.

Slow Cooker French Onion Gravy Turkey Breast

Prep 5 minCook 4 hRest 10 minTotal 4 h 15 minServes 6

Ingredients

• 3 lb turkey breast, boneless and skinless
• 2 cups yellow onion, thinly sliced
• 1 packet onion soup mix
• 2 cups turkey gravy, store-bought or made ahead

Instructions

1. Place the turkey breast into the bottom of the slow cooker insert. Ensure the meat is lying flat to promote even cooking throughout the process. Wash hands thoroughly after handling the raw poultry to prevent cross-contamination in the kitchen area.
2. Distribute the sliced onions evenly over the top of the turkey breast. Sprinkle the contents of the onion soup mix packet directly over the onions, ensuring an even coating across the surface of the meat.
3. Pour the turkey gravy over the turkey, onions, and soup mix. The gravy will act as a braising liquid, keeping the meat moist and flavorful while it cooks in the slow cooker. Cover the slow cooker with the lid.
4. Cook on the low setting for 4 to 6 hours or until the turkey reaches an internal temperature of 165°F (74°C). Once cooked, turn off the slow cooker and allow the meat to rest for at least 10 minutes before slicing to ensure the juices redistribute properly.
