  • 2 large russet potatoes
  • 1 medium sweet potato
  • 2 red bell peppers
  • 1 red onion
  • 1 large green zucchini
  • 1 large yellow squash
  • 3 cups marinara (for a homemade version see notes)
  • 5 cloves garlic, minced
  • ½ cup parmigiano regiano
  • ½ cup basil leaves, chiffonaded
  • salt and pepper, to taste


  • Slice the potatoes, sweet potato, red bell peppers, and red onion into thin rounds (about ⅛ inch). Slice the zucchini and squash into slightly thicker rounds (about ½ inch).
  • Pour one cup of the pasta sauce into the bottom of your slow cooker, then overlap the veggies in a circular pattern around the edges (i.e. potato, followed by sweet potato, followed by zucchini, bell peppers and onion, and repeat) until you’ve used them all. 
  • After each row add a dash of salt, pepper, and a bit of the minced garlic. Then layer more veg on top.
  • Pour the rest of the sauce on top and set the slow cooker on high for 3 hours. 
  • To serve, garnish with some fresh basil and parmigiana region. Leftovers will keep for about 3 days in the fridge.


For a homemade marinara sauce recipe that works just perfectly try out this one, and if you don't have heirloom tomatoes just sub in another variety.
