Crock Pot Potatoes Boulangere: A French Classic Made Easy

The aroma alone transports me back to a tiny, bustling bistro in the heart of Paris.

The anticipation was almost unbearable, and when that first bite of Potatoes Boulangere finally hit my tongue, it was pure, unadulterated comfort. The earthiness of the potatoes, the sweetness of the caramelized onions, and the rich, savory broth created a symphony of flavors that I’ve been chasing ever since. This Crock Pot version captures that same magic, with the added benefit of effortless preparation.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 8-10 hours (Low) / 4-5 hours (High)
• Total Time: 8 hours 15 minutes – 10 hours 15 minutes (Low) / 4 hours 15 minutes – 5 hours 15 minutes (High)
• Servings: 4-6
• Dietary Type: Gluten-Free

Ingredients

• 3 tablespoons butter
• 2 onions, thinly sliced
• ½ teaspoon dried thyme leaves
• 1 teaspoon sea salt
• ½ teaspoon fresh ground black pepper
• 6 potatoes, thinly sliced
• 1-2 cups chicken stock or 1-2 cups beef stock
• 1 cup Swiss cheese (optional) or 1 cup Gruyere cheese, shredded (optional)

Equipment Needed

• Slow cooker
• Skillet
• Knife
• Cutting board
• Baking dish (optional, for browning cheese)

Instructions

1. Begin by melting the butter in a skillet over medium heat. The butter will help to soften the onions and add a rich flavor to the dish.
2. Add the thinly sliced onions to the skillet and cook, stirring occasionally, until they are softened and translucent. This will take about 10-15 minutes. Don’t rush this step; allowing the onions to caramelize slightly will deepen their flavor.
3. Stir in the dried thyme leaves, sea salt, and fresh ground black pepper. Cook for another minute, allowing the herbs to bloom and release their fragrant oils. Remove the skillet from the heat.
4. Grease the inside of your slow cooker crock with butter or cooking spray. This will prevent the potatoes from sticking.
5. Create layers in the slow cooker. Start with a thin layer of the cooked onions on the bottom of the crock. Then, add a layer of the thinly sliced potatoes, slightly overlapping them. Repeat these layers of onions and potatoes until all the ingredients are used up, finishing with a layer of potatoes on top.
6. Pour the chicken stock or beef stock over the potatoes, ensuring that the liquid comes up to almost cover the top layer of potatoes. You may not need the full 2 cups; use just enough to nearly cover.
7. Cover the slow cooker and cook on low heat for 8 to 10 hours, or on high heat for 4 to 5 hours. The potatoes are done when they are tender and easily pierced with a fork.
8. If you’re using the optional cheese, carefully transfer the contents of the slow cooker to a baking dish. Sprinkle the Swiss cheese or Gruyere cheese evenly over the top.
9. Preheat your broiler. Place the baking dish under the preheated broiler and broil until the cheese is melted and bubbly, and lightly browned. This should only take a few minutes, so watch it closely to prevent burning.

Expert Tips & Tricks

• For even cooking, slice the potatoes and onions as thinly and uniformly as possible. A mandoline slicer can be very helpful for this.
• To prevent discoloration, soak the sliced potatoes in cold water while you’re preparing the other ingredients. This will also help remove some of the starch, resulting in a creamier texture.
• Make-ahead tip: You can prepare this dish through step 4 the night before. Cover the slow cooker insert and refrigerate it overnight. The next day, continue with step 5 and cook as directed. This is a great time-saver for busy weeknights.
• If the potatoes are not tender after the recommended cooking time, add a little more stock and continue cooking until they are done.
• For a richer flavor, use homemade stock instead of commercial stock.
• If you don’t have a broiler, you can skip browning the cheese or simply melt it by covering the slow cooker and letting it sit for a few minutes after the potatoes are cooked.

Serving & Storage Suggestions

Potatoes Boulangere is delicious served hot as a side dish alongside roasted chicken, grilled steak, or a hearty vegetarian main course. Garnish with fresh parsley or thyme for a pop of color and flavor.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until heated through. To prevent the potatoes from drying out, add a splash of stock or water before reheating. This dish is best enjoyed fresh, but it can also be frozen for longer storage. Thaw completely before reheating.

FAQs (Frequently Asked Questions)

Q: Can I use different types of potatoes?
A: Yes, Yukon Gold or Russet potatoes work well in this recipe. Avoid waxy potatoes like red potatoes, as they may not soften as much during the slow cooking process.

Q: Can I make this in the oven instead of a slow cooker?
A: Yes, you can. Layer the potatoes and onions in a baking dish, add the stock, and bake at 350°F (175°C) for about 1 hour 30 minutes, or until the potatoes are tender.

Q: The potatoes are still firm after the cooking time. What should I do?
A: Add more stock to the slow cooker and continue cooking until the potatoes are tender. Cooking times may vary depending on your slow cooker.

Q: Can I use pre-sliced potatoes?
A: While it’s preferable to slice the potatoes yourself for even thickness, you can use pre-sliced potatoes if you’re short on time. Just make sure they are thinly sliced.

Q: Can I add other vegetables to this dish?
A: Absolutely! Carrots, parsnips, or mushrooms would be great additions. Add them to the skillet with the onions.
