Ingredients You’ll Need for Sweet Potato Lasagna

• 2 large sweet potatoes, peeled and thinly sliced lengthwise
• 1 tablespoon olive oil
• 1 pound ground beef
• 1 small yellow onion, finely chopped
• 2 garlic cloves, minced
• 2 cups cooked butternut squash (or canned purée)
• 1/2 cup full-fat coconut milk
• 1 tablespoon nutritional yeast (optional for cheesy flavor)
• 1/2 teaspoon dried thyme
• 1/2 teaspoon dried basil
• 1/2 teaspoon sea salt
• 1/4 teaspoon black pepper (omit for strict AIP)
• Fresh parsley, for garnish

Ingredient Notes and Easy Variations

• Sweet potatoes: Orange sweet potatoes work best for their soft texture and natural sweetness.
• Ground beef: Choose grass-fed for a paleo-friendly, nutrient-rich option.
• Butternut squash: Adds creaminess and replaces tomato sauce. Substitute with roasted pumpkin if desired.
• Nutritional yeast: Offers a cheesy flavor without dairy; omit for AIP compliance.
• Coconut milk: Use full-fat canned for the creamiest sauce.

For a variation, try our AIP sweet potato hash as a breakfast-friendly version of this concept.

Kitchen Equipment You’ll Need

• Mandoline or sharp knife (for slicing sweet potatoes)
• Large skillet
• Blender or food processor
• Baking dish (9×13-inch)
• Foil or parchment paper
• Measuring cups and spoons
• Spatula

Having a sharp mandoline makes prepping sweet potatoes faster and more uniform — key for even layering.

Step-by-Step Preparation: How to Make Sweet Potato Lasagna

Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil.

Step 2: Peel and slice sweet potatoes lengthwise into thin strips, about 1/8-inch thick. Set aside.

Step 3: In a large skillet over medium heat, sauté chopped onions until soft. Add garlic and cook for 1 more minute.

Step 4: Add ground beef to the skillet, breaking it up with a spoon. Season with thyme, basil, salt, and pepper (if using). Cook until browned and no longer pink.

Step 5: While beef cooks, make the squash sauce. In a blender, combine butternut squash, coconut milk, nutritional yeast, and a pinch of salt. Blend until smooth and creamy.

Step 6: Begin layering the lasagna: Add a thin layer of squash sauce to the bottom of your baking dish. Add a single layer of sweet potato slices, then spoon over a layer of cooked beef. Repeat layers until all ingredients are used, finishing with a generous layer of squash sauce on top.

Step 7: Cover tightly with foil and bake for 45–50 minutes until sweet potatoes are tender. Remove foil and bake an additional 10 minutes to lightly brown the top.

Step 8: Let cool for 10 minutes before slicing. Garnish with fresh parsley and serve warm.

Pair with a side like cucumber Caesar salad or delicious apple fruit salad for extra freshness.

Pro Tips for the Best Paleo Lasagna

• Use uniform slices for even cooking. A mandoline helps greatly.
• Let the lasagna rest after baking to set layers and enhance flavor.
• Add a little extra coconut milk if the squash sauce seems too thick.
• Brown the beef well — caramelization adds deep flavor.
• For freezer meals, assemble and freeze before baking.

This is a great make-ahead meal just like our freezer breakfast sandwiches.

Common Mistakes to Avoid

• Slicing potatoes too thick: They won’t cook through and will be chewy.
• Using watery squash: Drain or cook down excess moisture for a thick sauce.
• Overloading the layers: Keep layers even for proper cooking and slicing.
• Not seasoning each layer: Sweet potatoes are neutral — flavor is key!

Serving Suggestions

Serve your sweet potato lasagna with:

• Fall fruit salad for a fresh, seasonal side
• Roasted veggie medley
• High protein bagels for a grain-free twist
• A light dessert like pumpkin cream puffs

This dish is hearty enough to stand alone, but sides make it feel special.

Creative Presentation Ideas

• Serve in individual ramekins for dinner parties.
• Top each slice with a swirl of extra squash sauce and parsley.
• Garnish with toasted pumpkin seeds for crunch and color.

Flavor Variations and Add-Ins

• Italian-style: Add sautéed mushrooms, spinach, or zucchini to the beef layer.
• Tex-Mex twist: Season beef with cumin and oregano, top with avocado.
• Chicken version: Use ground chicken or turkey for a leaner protein.
• Vegan option: Replace beef with lentils or a vegan pasta salad.

Craving a sweet finish? Try cinnamon roll breakfast bake for dessert.

How to Store and Reheat

• Store in an airtight container in the fridge for up to 4 days.
• Reheat in the oven at 350°F for 15–20 minutes, or microwave individual servings.
• To freeze: assemble unbaked, cover well, and freeze for up to 2 months.

This is an excellent option for meal prep fans.

Make-Ahead Tips for Busy Nights

• Slice sweet potatoes and refrigerate in water for up to 2 days.
• Cook beef and squash sauce up to 3 days in advance.
• Fully assemble the dish and refrigerate up to 24 hours before baking.

You can even bake and freeze whole — it reheats beautifully just like our crack breakfast casserole.
