Ah, Sweet Potato Mayo Gratin—a creamy, cheesy, slightly sweet side dish that’s rich, golden, and perfect for holiday tables or cozy dinners. Using mayo instead of cream gives it a luscious texture with a subtle tang. Here’s a detailed guide:
Ingredients
- 3–4 medium sweet potatoes, peeled and thinly sliced
- 1/2 cup mayonnaise
- 1/2 cup milk (optional, for creaminess)
- 1–2 cloves garlic, minced (optional)
- 1 cup shredded cheese (Gruyère, cheddar, or mozzarella work well)
- Salt & pepper – to taste
- Optional toppings: breadcrumbs, fresh thyme, or paprika
Step-by-Step Cooking
- Preheat oven:
- 375°F (190°C). Grease a 9×13-inch baking dish.
- Prepare the sauce:
- In a small bowl, mix mayonnaise, milk (if using), garlic, salt, and pepper until smooth.
- Layer the sweet potatoes:
- Arrange a layer of sweet potato slices in the baking dish.
- Spread a thin layer of the mayo mixture over the potatoes.
- Sprinkle a little cheese on top.
- Repeat layers until all potatoes, mayo mixture, and cheese are used.
- Top the gratin:
- Finish with a generous layer of cheese.
- Optional: sprinkle breadcrumbs or paprika for a golden crust.
- Bake:
- Cover with foil and bake 30–35 minutes.
- Remove foil and bake an additional 15–20 minutes until potatoes are tender and top is golden brown.
- Serve:
- Let rest 5–10 minutes before serving so it sets nicely.
Tips
- Slice sweet potatoes thinly (1/8–1/4 inch) for even cooking.
- Mayo adds tang and richness without needing heavy cream.
- Can be prepared ahead of time and baked just before serving.
- Add herbs like thyme or rosemary for extra depth of flavor.
