AIP beef and kale casserole - skillet then oven, iron and leafy-green main dish

Some nights the only realistic goal is one pan and minimal cleanup. This casserole is built around that goal: ground beef and vegetables brown in a skillet, kale gets folded in until it collapses down to almost nothing, and the whole thing finishes in the oven while you do something else for 15 to 20 minutes. It is plain, and it gets dinner made on a night when that alone is the win.

Beef is one of the most straightforward whole-food sources of iron, the kind of steady nutritional weight that matters on a protocol asking a lot of a body over many months. The kale folds in for volume and color as much as anything, and by the time it collapses into the pan it has given the dish a real vegetable backbone instead of an afterthought.

Choose beef from an animal that lived well if you are able to, and let that sit with you as you brown it. Plate it so the kale's green shows against the sweet potato's orange, and pause a moment before the fork goes in.

Ingredients

• 3 tbsp olive oil, divided
• 1.5 cups sweet potato, chopped into small cubes
• 1 small yellow onion, sliced
• 3 cloves garlic, sliced
• 1/2 cup celery, diced
• 1 lb ground beef
• 1 tsp dried basil
• 1 tsp dried oregano
• 1 tsp dried thyme
• 1 tsp dried rosemary
• 1 tsp sea salt
• 3 tbsp nomato sauce or coconut aminos
• 5 to 6 cups lacinato or curly kale, chopped
• 1 cup dairy-free cheese sauce, optional (see Core note)

Method

Heat the oven to 375 F.

Warm about 2 tbsp of the olive oil in a large oven-safe skillet over medium heat. Add the sweet potato cubes and cook, stirring now and then, until they begin to soften and take on color, around 8 to 10 minutes. Add the sliced onion, garlic, and celery and cook another few minutes until the onion is soft and fragrant.

Push the vegetables to the side, add the remaining olive oil, and add the ground beef. Break it up and let it brown. Stir in the dried basil, oregano, thyme, rosemary, and sea salt. Once the beef is cooked through, stir in the nomato sauce or coconut aminos.

Fold in the chopped kale a few handfuls at a time, letting each batch wilt down before adding more. It will look like far too much kale and then collapse into the pan. If you are using the dairy-free cheese sauce, spoon it over the top now.

Move the skillet to the oven and bake until everything is hot through and the topping is set, about 15 to 20 minutes. Let it rest a few minutes before serving.

Stovetop variation

You can keep this entirely on the stovetop. After folding in the kale, cover the skillet, drop the heat to low, and let it steam for 5 to 8 minutes until the kale is fully tender. Stir the cheese sauce through at the end instead of baking it on top.

Core note on swaps

The source recipe notes that the dairy-free cheese sauce should be made without paprika for AIP, and we go further: paprika is a nightshade and is fully excluded on AIP Core, so any cheese sauce you use must be both nutritional-yeast-free and nightshade-free. If you do not have a compliant sauce, leave it out entirely; the casserole stands on its own. Use nomato sauce (not tomato, which is a nightshade) or simply coconut aminos for the savory depth.
