Sweet Potato Lasagna with Ground Beef

Meal prep magic right here — layers of sweet potato, seasoned ground beef, and creamy yogurt sauce that actually tastes better the next day.

Instructions

  1. 1

    Preheat your oven to 200°C. Slice the sweet potatoes into thin rounds, about 5mm thick.

  2. 2

    Heat a large pan and brown the ground beef with diced onion until the meat is cooked through and the onion is soft. Season with salt, pepper, paprika, cayenne, chili powder, and garlic powder to taste.

  3. 3

    Add the canned tomatoes and crumbled bouillon cube to the meat mixture. Let it simmer for 10-15 minutes until the sauce thickens slightly.

  4. 4

    Meanwhile, mix the Greek yogurt with 25g cheese, basil, and oregano for your white sauce.

  5. 5

    Layer half the sweet potato slices in a baking dish, then spread the meat mixture on top, followed by the remaining sweet potatoes. Dot the yogurt sauce over the top and sprinkle with the remaining 100g cheese.

  6. 6

    Bake for 30-40 minutes until the sweet potatoes are tender and the top is golden. Let it cool slightly before dividing into 4 meal prep containers.

Tips from the kitchen

  • Slice the sweet potatoes as evenly as you can at that 5mm thickness. Thick rounds stay hard in the middle while everything else gets soft, so a mandoline helps if you have one.
  • Let the meat sauce actually simmer down for the full 10 to 15 minutes. If it's still watery when you layer it, the lasagna ends up soupy and the slices won't hold.
  • Keep the yogurt sauce dotted on top, not spread into a thick blanket. Greek yogurt can split if it bakes too long in a heavy layer, so small spoonfuls work better.
  • Check the sweet potatoes with a knife before pulling it out. The top can look golden at 30 minutes while the bottom layer is still firm, so go closer to 40 if a blade meets any resistance.
  • Cool it for a good 10 minutes before cutting into the containers. Hot out of the oven it falls apart, but a short rest lets the layers settle.

Ways to vary it

  • Swap the ground beef for ground turkey or chicken if you want something lighter. Keep the same spice mix so it doesn't taste flat.
  • For a bit of green, you can layer in a handful of baby spinach between the meat and the top sweet potatoes. It wilts down to almost nothing as it bakes.
  • If you like more heat, lean harder on the cayenne and chili powder. The sweet potato takes the edge off nicely.

Storage & leftovers

Keeps in the fridge for up to 4 days, and honestly it tastes better on day two once the flavors settle. It freezes well in the meal prep containers for about 3 months. Reheat in the microwave or a 180°C oven until hot through, and cover it loosely so the top doesn't dry out.

What to serve with it

A simple green salad with a sharp vinaigrette cuts through the sweetness of the potato. Some crusty bread on the side is nice if you want to mop up the sauce.
