FAQs
Can I make this casserole without a slow cooker?
Yes, you can assemble the ingredients in a baking dish, cover with foil, and bake at 350°F (175°C) for about 1.5 to 2 hours or until the potatoes are tender.
Can I use fresh tomatoes instead of canned?
Fresh tomatoes can be used, but you may need to adjust cooking time and add a bit of tomato sauce or broth to maintain moisture, as canned diced tomatoes contain liquid that helps cook the casserole evenly.
