Wholesome Ingredients for This Crockpot Lasagna
Each ingredient in this slow cooker lasagna with ground beef was chosen to maximize both flavor and nutrition. Here are a few of the key players:
- Lean ground beef: We used 90-93% lean ground beef to ensure plenty of protein while keeping the fat content in check. Sub in ground turkey for an even leaner option.
- Fresh spinach: Adding chopped spinach boosts fiber and essential nutrients. Frozen spinach works in a pinch; just be sure to thaw and squeeze out any excess water.
- Whole-grain or gluten-free noodles: Regular uncooked lasagna noodles work perfectly here. For a healthier twist, try whole-wheat noodles or gluten-free alternatives.
- Cottage cheese: A lighter swap for ricotta cheese, cottage cheese adds creaminess along with a hit of protein.
Pro Tip: Look for a marinara sauce with minimal added sugar (5 grams or less per serving). It’s an easy way to keep this dish on the healthier side.

Our Team’s Tips for the Best Crockpot Lasagna
- Add the water to your marinara jar, shake, and pour to get every last bit of sauce while adding flavor to the dish.
- Avoid stirring too much during cooking to keep the layers intact.
- For meal prep, portion leftovers into airtight containers and refrigerate for up to 4 days, or freeze for up to 3 months.

Crockpot Lasagna FAQs
Can I use no-boil noodles in this recipe?
Yes, but you’ll need to reduce the water slightly. Regular noodles work best to absorb the liquids as they cook.

Ground turkey or chicken works wonderfully. For a plant-based option, try lentils or finely chopped mushrooms.
How do I make this a vegan recipe?
Replace the ground beef with lentils, the cheese with plant-based alternatives, and ensure your marinara sauce is vegan-friendly.
