Introduction

This Gratin de haché et patate douce is a comforting and flavorful dish combining tender sweet potatoes with savory minced meat. Baked with creamy sauce and melted cheese, it makes a perfect family meal that’s both hearty and delicious.

A white rectangular dish filled with a layered baked casserole. The bottom layer is a rich, dark brown ground meat mix with visible small chunks and a glossy texture. Above it is a creamy, melted layer of white cheese that stretches slightly where it meets the meat. The top layer features golden-brown baked cheese slices with slightly crispy edges, interspersed with soft orange-tinted slices of vegetables or cheese. Fresh green herb sprigs, likely parsley and thyme, are scattered on top, adding a fresh contrast. The dish rests on a wooden board, with blurred red and yellow tomatoes in the background on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

800g sweet potatoes
400g minced meat (chicken or beef)
1 large onion, sliced
2 garlic cloves, minced
200ml crème fraîche
100g grated cheese (such as cheddar)
200ml vegetable broth
1 teaspoon mild chili powder or paprika
Salt and pepper to taste

Instructions

Step 1: Preheat your oven to 180°C (350°F).
Step 2: Peel and slice the sweet potatoes thinly, about 3 mm thick.
Step 3: In a large skillet, heat a little olive oil and sauté the sliced onion until translucent, then add the minced garlic and cook briefly.
Step 4: Add the minced meat to the skillet and cook over medium heat for 5 to 7 minutes until it is well browned.
Step 5: Stir in the chili powder or paprika, and season with salt and pepper according to your taste.
Step 6: In a baking dish, spread half of the sliced sweet potatoes evenly over the bottom.
Step 7: Layer the cooked meat mixture over the sweet potatoes, then cover with the remaining sweet potato slices.
Step 8: Pour the crème fraîche evenly over the layers.
Step 9: Pour the vegetable broth uniformly over the top.
Step 10: Generously sprinkle the grated cheese over the surface of the gratin.
Step 11: Bake in the preheated oven for about 40 minutes, or until the top is golden and bubbling.
Step 12: Allow the gratin to rest for a few minutes before serving. It pairs beautifully with a fresh green salad.

Tips & Variations

For extra flavor, add fresh herbs like thyme or rosemary to the meat mixture.
You can substitute crème fraîche with sour cream or Greek yogurt for a tangier taste.
Try adding a pinch of nutmeg or cinnamon to the sweet potatoes for a warm, aromatic note.
Use mozzarella or gruyère cheese as an alternative to cheddar for different melting textures.
If using beef, lean cuts help reduce excess fat, keeping the dish lighter.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm in the oven at 160°C (320°F) for about 15-20 minutes until heated through, which helps maintain its texture better than microwaving.

How to Serve

FAQs

Can I prepare this gratin in advance?

Yes, you can assemble the gratin a few hours beforehand and keep it covered in the refrigerator. Just bake it before serving, adding a few extra minutes to the cooking time if chilled.

Can I use regular potatoes instead of sweet potatoes?

Absolutely. Regular potatoes work well and provide a different flavor profile. Adjust cooking times slightly as regular potatoes may require a bit longer to soften.
