Potato Topped Low Sodium Ground Beef and Tomato Casserole
This low sodium ground beef and tomato casserole is a small-batch, comfort-forward meal made for one or two. It uses no-salt-added tomatoes and low-sodium broth so you can control salt and make a gentle to chew dish.

This casserole is convenient when you want one warm, balanced dish without leftovers piling up. The recipe uses a single skillet and a small ovenproof dish so you can cook the beef and finish everything in one pan if you prefer.
Portions are scaled for one or two, and textures are easy to adjust. Cook the potato until very soft and mash smooth for easier chewing, or leave it chunky if you like a bit more bite.
Ingredients You’ll Need

- 8 ounces lean ground beef (about 1 cup)
- 1 small Yukon Gold potato, peeled and cut into chunks (about 8 ounces)
- 1/2 cup no-salt-added diced tomatoes and 1/3 cup low-sodium vegetable broth
Optional additions include a tablespoon of plain Greek yogurt or milk to loosen the mash, 2 tablespoons shredded cheese, and fresh parsley. Serve with steamed soft vegetables, soft bread, or a light salad if desired.
Step-by-Step Recipe

- Preheat oven to 375 F or prepare a covered skillet for stovetop finishing. Sauté onion in olive oil 3 to 4 minutes, add ground beef and cook until no longer pink, drain excess fat, then add garlic, tomatoes, tomato paste if using, broth, Italian seasoning, and pepper and simmer 5 minutes.
- Place potato chunks in a small pot, cover with cold water, bring to a boil and simmer until very tender about 10 to 12 minutes. Drain and mash with Greek yogurt or milk until smooth, adding a little liquid to reach a soft spreadable texture.
- Spoon the meat and tomato mixture into an ovenproof dish or keep it in the skillet, spread the mashed potato over the top and sprinkle cheese if using. Bake 12 to 15 minutes until heated through and cheese is melted, or cover and simmer on the stovetop 8 to 10 minutes. Let sit 3 minutes, garnish with parsley, and serve warm.
