Tips for success
For a deeper flavor, you can briefly sear the sausages in a hot pan before placing them in the slow cooker, though this step is optional. If you choose to sear them, ensure they are browned on all sides, but do not cook them through, as the slow cooker will finish the process. This adds an extra layer of complexity to the final sauce, creating a richer base that pairs beautifully with the sweetness of the tender leeks.
If you prefer a thicker sauce, you can remove the sausages once they are cooked and set them aside, then whisk a small amount of cornstarch mixed with cold water into the remaining liquid in the slow cooker.
Turn the setting to high for 10-15 minutes until the sauce reduces and thickens to your desired consistency. This simple adjustment can elevate the presentation and ensure that the sauce clings perfectly to the sausages and leeks when served on the plate.
Variations
- Mustard and Herb Version: Stir in two tablespoons of fresh chopped thyme and parsley to the sauce before serving. This adds a vibrant herbal note that complements the sharpness of the Dijon mustard perfectly.
- Creamy Mustard Sauce: Whisk in a quarter cup of heavy cream after the sausages have finished cooking. This creates a richer, more luxurious sauce that coats the leeks beautifully.
Storage and make-ahead
- Fridge
- Keep in an airtight container in the refrigerator for up to 3 days. Ensure the leftovers are cooled completely before sealing and refrigerating.
- Freezer
- Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating thoroughly.
- Reheat
- Reheat gently in a covered pan on the stovetop over low heat until the internal temperature reaches 165°F (74°C), or in a preheated 350°F oven until hot.
Transfer any leftovers to an airtight container once they have cooled to room temperature, which should take no longer than 2 hours. Store the sausages and leeks together in their sauce to keep them moist and prevent them from drying out.
Properly stored, the dish will remain fresh in the refrigerator for up to 3 days, making it an excellent option for meal planning or quick future dinners that require minimal effort to reheat.
This dish is an excellent candidate for making ahead, as the flavors often deepen and improve after sitting for a day. You can prepare the entire recipe in advance, allow it to cool completely, and then store it in the refrigerator.
When you are ready to serve, simply reheat the sausages and leeks gently on the stovetop or in the oven until they are heated through. This makes it a stress-free option for hosting or busy work weeks.
Serving ideas
Serve the andouillettes hot, placed directly over a generous portion of the creamy, braised leeks. The sauce from the pot should be spooned over the top of the sausages to add extra moisture and flavor. This dish pairs exceptionally well with crusty bread, which is perfect for mopping up the remaining white wine and mustard sauce, or a simple side of buttered potatoes or steamed green beans to round out the meal perfectly.
Consider plating the meal on warmed plates to ensure the sausages and leeks stay at the optimal serving temperature throughout the meal. A sprinkle of fresh parsley or chives can add a touch of color and brightness to the final presentation, though it is purely decorative.
The simplicity of the dish allows it to stand on its own, but serving it with a crisp green salad with a light vinaigrette can provide a refreshing contrast to the richness of the meat.

Slow Cooker Andouillettes with Creamy Leeks

Ingredients
- 4 andouillettes
- 3 cups leeks, cleaned and sliced
- 2 cloves garlic, minced
- 1/2 cup dry white wine
- 2 tbsp Dijon mustard
Instructions
- Place the raw andouillettes at the bottom of the slow cooker insert. Evenly scatter the sliced leeks over the sausages to provide a flavorful bed for cooking. Sprinkle the minced garlic over the leeks to ensure the aromatics distribute evenly during the braising process.
- In a small glass measuring cup, whisk together the white wine and Dijon mustard until the mixture is smooth and fully emulsified. Pour this mixture evenly over the sausages, leeks, and garlic. Cover the slow cooker with its lid and set to low heat for 4 hours.
- Check that the internal temperature of the sausages has reached 160°F (71°C) to ensure they are fully cooked. Once the sausages are ready, remove them carefully and let them rest for at least 5 minutes before serving alongside the tender, creamy leeks from the pot.
