Crockpot Creamy Dijon Turkey Tenderloin Tips, FAQ & printable recipe

Tips for success

To enhance the flavor of the sauce, you can deglaze the slow cooker insert with a splash of white wine or chicken stock before adding the other ingredients, scraping up any browned bits that might have formed if you chose to sear the turkey first.

This adds a layer of complexity that complements the sharpness of the Dijon mustard perfectly.

If you find the sauce is too thin after the cooking time, remove the turkey and whisk the sauce in the slow cooker with a small amount of cornstarch slurry, then heat on high for an additional 10 minutes. This will quickly thicken the liquid into a luxurious gravy that is perfect for serving over mashed potatoes or steamed vegetables.

Variations

• Mushroom Dijon Turkey: Add 8 ounces of sliced cremini mushrooms during the layering phase to introduce a deep, earthy flavor that pairs beautifully with the creamy mustard sauce.
• Herbed Garlic Turkey: Incorporate 3 cloves of minced garlic and a teaspoon of fresh rosemary into the sauce for a more aromatic and robust herb profile that complements the turkey.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days.

Freezer

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

Reheat

Gently reheat in a saucepan over low heat, adding a tablespoon of water or broth to loosen the sauce if it has thickened too much during storage.

Store any leftovers in an airtight container to maintain moisture. The turkey can be kept in the refrigerator for up to three days. When storing, keep the turkey submerged in the sauce to prevent it from drying out, which helps preserve the texture and flavor for when you are ready to reheat it for a quick meal.

This dish is excellent for preparation in advance, as the flavors continue to meld and develop in the refrigerator overnight.

You can assemble the ingredients in the slow cooker insert, keep it covered in the fridge, and simply place it in the base to cook when you are ready. This makes it an ideal choice for busy schedules or planned dinners.

Serving ideas

Serve the sliced turkey tenderloin warm, generously ladled with the creamy Dijon sauce directly from the slow cooker.

It pairs exceptionally well with sides that can soak up the extra sauce, such as roasted root vegetables, buttery mashed potatoes, or a simple side of steamed green beans for a fresh contrast to the rich, tangy mustard profile.

For a more elegant presentation, arrange the sliced turkey in a fan pattern on a large platter and drizzle the creamy sauce over the top, garnishing with an extra sprinkle of fresh thyme if desired.

Ensure each serving gets a good portion of the softened onions, which add a delightful sweetness that balances the acidity of the Dijon sauce.

Ingredients

• 1 1/2 lb turkey tenderloins
• 1 large yellow onion, sliced
• 1 tsp dried thyme
• 1 cup creamy Dijon sauce

Instructions

1. Place the turkey tenderloins into the base of the slow cooker, arranging them side by side to ensure even cooking. Layer the sliced onions over the top of the turkey to provide a flavor base that will soften during the cooking process.
2. Sprinkle the dried thyme evenly over the onions and turkey. Pour the creamy Dijon sauce over the entire mixture, ensuring that all pieces are well-coated to keep the meat moist during the long cooking time.
3. Cover the slow cooker and cook on low for 4 hours. Once finished, check that the turkey has reached an internal temperature of 165°F (74°C). Remove the turkey to a carving board and let it rest for at least 5 minutes before slicing and serving with the warm sauce.
