Busy nights do not have to mean skipping out on comfort food. This slow cooker lasagna delivers all the classic flavors with way less effort. Layer everything up in the crockpot and by dinner time you have cheesy saucy goodness ready to serve. I have found this to be my go-to on nights when stovetop juggling just is not going to happen.

My first try at crockpot lasagna was on a chilly Monday when time got away from me. Everyone raved and now it is part of our monthly rotation.

Ingredients

  • Ground beef: for hearty flavor and protein try to pick grass-fed or lean beef for the best taste
  • Sweet onion: layers in subtle sweetness go for firm and glossy onions with no soft spots
  • Garlic: packs in aromatic depth use fresh for the boldest flavor
  • Marinara sauce: adds tangy tomato base choose one with minimal added sugar
  • Tomato paste: thickens and intensifies flavor always look for deep red color in the tube or can
  • Dried Italian seasoning: rounds out the sauce with herby notes make sure it smells fresh before using
  • Lasagna noodles: bring structure to each layer I find regular noodles work great in the slow cooker—no boiling needed
  • Ricotta cheese: creates creamy pockets between the noodles whole milk ricotta makes for a richer dish
  • Shredded mozzarella: melts into gooey stretches always buy blocks and shred fresh for best melt
  • Shredded Parmesan: brings salty sharpness select Parmigiano Reggiano if possible for the most flavor
  • Fresh parsley: adds freshness to balance the richness pick bright green bunches with no yellowing
  • Salt: ties all the flavors together use fine sea salt for even seasoning

My favorite part is the cheesy corner pieces always the ones claimed first in my house The first time I made this my youngest insisted on licking the spoon after every cheesy layer.
