- 2 cups sweet potatoes, thinly sliced (1/8″ thick) (260 g) – mandoline recommended for consistent thickness
- 2 tablespoons butter (28 g) – or olive oil for a different flavor profile
- 2 tablespoons flour (15 g) – use gluten-free flour blend for a GF version
- 1 cup whole milk (460 g) – almond milk works for a dairy-sensitive option
- 3 tablespoons creme fraiche (45 g) – sour cream can substitute in a pinch
- 1/2 teaspoon nutmeg (2 g) – freshly grated if possible

How to Make Individual Sweet Potato Gratins with Creme Fraiche, Onions, and Bacon – Step by Step
Step 1:
Preheat your oven to 375°F (190°C) and lightly grease four 8-oz ramekins or gratin dishes.
Step 2:
Using a mandoline or sharp knife, slice the sweet potatoes into very thin rounds (about 1/8-inch thick). Set aside.
Step 3:
In a medium skillet over medium heat, cook the diced bacon until it begins to crisp, about 5-6 minutes.
Step 4:
Add the diced onions to the bacon and continue cooking until the onions become translucent and start to caramelize, about 3-4 minutes.
Step 5:
Stir in the minced garlic and cook for another 30 seconds until fragrant. Remove from heat and set aside.
Step 6:
In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour to create a roux, cooking for about 1 minute until it smells slightly nutty but hasn’t browned.
Step 7:
Gradually whisk in the milk, ensuring no lumps form. Bring to a gentle simmer, stirring constantly, until the mixture thickens enough to coat the back of a spoon.
Step 8:
Remove from heat and stir in the creme fraiche, nutmeg, brown sugar, salt, and pepper until smooth and well combined.
Step 9:
Layer about 1/4 cup of sweet potato slices in the bottom of each prepared ramekin, slightly overlapping the edges.
Step 10:
Sprinkle each with some of the bacon-onion mixture, then drizzle with 2 tablespoons of the cream sauce.
Step 11:
Repeat the layers (sweet potatoes, bacon-onion mixture, sauce) until all ingredients are used, finishing with a layer of cream sauce on top.
Step 12:
Sprinkle each gratin with grated Parmesan cheese.

Frequently Asked Questions
Can I make these Individual Sweet Potato Gratins with Creme Fraiche, Onions, and Bacon ahead of time?
Yes! You can assemble these gratins up to 24 hours in advance and store them covered in the refrigerator. When ready to bake, add about 10 extra minutes to the cooking time since they’ll be starting cold.
Can I substitute regular potatoes for sweet potatoes?
Absolutely. Yukon Gold or Russet potatoes work well in this recipe, though you’ll want to adjust the sweet element (reduce or omit the brown sugar) since regular potatoes don’t have the natural sweetness of sweet potatoes.
What can I use instead of creme fraiche?
If you can’t find creme fraiche, sour cream is the best substitute. Greek yogurt will also work but will add more tanginess to the dish.
Can I make one large gratin instead of individual servings?
Yes! Use a 2-quart baking dish and follow the same layering instructions. You may need to increase the baking time by about 15 minutes to ensure the sweet potatoes in the center are fully cooked.

These Individual Sweet Potato Gratins with Creme Fraiche, Onions, and Bacon transform humble sweet potatoes into an elegant, indulgent dish worthy of special occasions yet simple enough for everyday meals.
