Ingredients

Ground beef (80–85% lean)– 2 pounds
Condensed tomato soup – 2 cans (10.5 ounces each)
Frozen diced potatoes O’Brien (with onions and peppers) – 3 cups, thawed
Whole milk – 1 cup
Salt – 1 teaspoon
Black pepper – ½ teaspoon (optional, for a little extra warmth)

Ingredient Notes

What is potatoes O’Brien?Potatoes O’Brien are diced potatoes mixed with diced onions and red and green bell peppers. They’re sold frozen in most grocery stores (often near the hash browns and other frozen potatoes). The onions and peppers add flavor and color without any extra chopping.

Can I use regular frozen diced potatoes instead? Yes. If you can’t find potatoes O’Brien, use 3 cups of frozen diced hash browns and add ½ cup of diced onion and ¼ cup of diced bell pepper. The flavor will be slightly different but still delicious.

What kind of ground beef? 80–85% lean is ideal. The fat adds flavor and keeps the casserole moist. Leaner beef (90/10 or 93/7) will work but may produce a drier casserole. If using lean beef, consider adding 2 tablespoons of olive oil or butter to the dish.

Why use condensed tomato soup?Condensed tomato soup is thick and concentrated. When mixed with milk, it creates a creamy, tangy sauce that’s perfect for this casserole. Do not add water — the milk provides the right consistency. Do not use “healthy” or low-sodium versions unless you adjust the seasoning.

Why whole milk? Whole milk creates the richest, creamiest sauce. 2% milk works but will be thinner. Skim milk is not recommended — the sauce may be watery. For an even richer casserole, use half-and-half.

Do I need to thaw the potatoes O’Brien? Yes. Thawing them ensures they cook evenly in the casserole. You can thaw them in the microwave or let them sit at room temperature while you prep the other ingredients.

Do I need to brown the ground beef first? No. The beef goes into the casserole raw and cooks in the oven. This saves time and cleanup. The beef will be fully cooked after 65–70 minutes in the oven.

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C) .

Lightly grease a deep 9×13-inch casserole dish or any deep baking dish of similar size with nonstick spray or a thin layer of oil.

Step 2: Layer the Raw Ground Beef

Crumble the 2 pounds of raw ground beefevenly into the bottom of the prepared casserole dish. Break it up with your fingers so it covers the bottom in a loose, even layer.

Do not brown it first — it will cook in the oven.

Step 3: Add the Potatoes

Sprinkle the 3 cups of thawed frozen diced potatoes O’Brienevenly over the raw ground beef. Spread them out so you get a bit of potato, onion, and pepper in every bite.

Step 4: Make the Tomato Sauce

In a mixing bowl or large measuring cup, whisk together:

2 cans condensed tomato soup
1 cup whole milk
1 teaspoon salt
½ teaspoon black pepper (if using)

Whisk until smooth and well combined.

Step 5: Pour the Sauce Over the Casserole

Pour the tomato soup mixture slowly and evenly over the raw ground beef and potatoes in the casserole dish. Cover the surface so the liquid can seep down through the meat and vegetables.

Use the back of a spoon to gently press down any potatoes that are sticking up above the liquid so they can pick up some of the sauce as it bakes.

Do not stir the layers together.The sauce will penetrate as it cooks.

Step 6: Cover and Bake

Cover the casserole dish tightly with foil. This helps the beef cook through and the potatoes become tender without drying out.

Bake, covered, in the preheated oven for 45 minutes.

Step 7: Uncover and Finish Baking

Carefully remove the foil (watch for steam). Continue baking uncovered for another 20 to 25 minutes.

The casserole is ready when:

It is bubbling around the edges
The beef is cooked through in the center (no pink remaining)
The potatoes are tender when pierced with a fork

Step 8: Rest and Serve

Let the casserole rest for 10 minutes after you take it out of the oven. This allows the juices to settle and the casserole to firm up slightly, making it easier to scoop.

Taste and adjust seasoning with a little more salt or pepper if needed. Serve hot.

Variations & Tips

Add Cheese

Sprinkle 1 cup of shredded cheddar, Colby Jack, or mozzarella cheese over the top during the last 10 minutes of baking (uncovered). The cheese will melt into a golden, bubbly topping.

Add Vegetables

Add to the casserole along with the potatoes:

1 cup frozen corn – Adds sweetness
1 cup frozen peas – Adds color and sweetness
1 cup sliced mushrooms – Adds earthy depth
1 cup diced carrots – Adds sweetness and color

Make It Spicy

Add ½ teaspoon of cayenne pepper to the tomato sauce
Add 1 teaspoon of red pepper flakes
Use diced tomatoes with green chilesinstead of plain tomato soup (adjust liquid accordingly)
Top with sliced pickled jalapeños

Make It with Cream of Mushroom Soup

For a different flavor profile, substitute 1 can of cream of mushroom soup for 1 can of the tomato soup. The result will be a creamy, savory, less-tangy casserole.

Make It with Ground Turkey

Substitute 2 pounds of ground turkey for the ground beef. Add 2 tablespoons of olive oil to the dish to compensate for the lower fat content. The cooking time remains the same.

Make It in the Slow Cooker

Layer the raw ground beef and potatoes O’Brien in the slow cooker.
Whisk together tomato soup, milk, salt, and pepper. Pour over the top.
Cook on LOW for 6–7 hoursor HIGH for 3–4 hours.
For a thicker sauce, remove the lid during the last hour of cooking.

Make It Gluten-Free

Use gluten-free condensed tomato soup(several brands make it). The ground beef and potatoes are naturally gluten-free.

Storage & Reheating

Refrigerator: Store leftovers in an airtight container for up to 5 days. The flavors deepen overnight — this casserole is often even better the next day.

Reheating:

Microwave: 1–2 minutes per serving.
Oven: 350°F for 10–15 minutes, covered with foil to prevent drying out.
Skillet: Warm over medium-low heat, adding a splash of milk or broth if the casserole is too thick.

Freezing: This casserole freezes beautifully for up to 3 months. Assemble the casserole completely (but don’t bake), cover tightly with foil, and freeze. When ready to bake, thaw overnight in the refrigerator, then bake as directed (add 10–15 minutes to the baking time). You can also freeze baked leftovers — the texture may soften slightly, but the flavor remains excellent.

Frequently Asked Questions (FAQs)

Do I need to brown the ground beef first?

No. The beef goes into the casserole raw and cooks in the oven. This is a time-saving, one-dish method. The beef will be fully cooked after 65–70 minutes at 375°F.

Why do I need to thaw the potatoes O’Brien?

Thawing ensures they cook evenly. Frozen potatoes can release excess water as they thaw in the oven, which can make the casserole watery. Thawing them first allows you to drain any excess moisture.

Can I use fresh potatoes instead of frozen?

Yes. Use 3 cups of diced fresh potatoes (about 3 medium potatoes). Add ½ cup of diced onion and ¼ cup of diced bell pepper. You may need to add an extra ¼ cup of milk, as fresh potatoes release less moisture than frozen.

Why is my casserole watery?

A few possibilities:

You didn’t thaw the potatoes O’Brien first (frozen potatoes release water as they thaw)
You used low-fat or skim milk (whole milk is best)
You didn’t bake it long enough uncovered (the sauce needs time to reduce)

Why is my casserole dry?

A few possibilities:

You used very lean ground beef (90/10 or leaner)
You overbaked it (check at 65 minutes total bake time)
You used too many potatoes or not enough sauce

Can I add cheese to this?

Absolutely. Sprinkle 1 cup of shredded cheddar over the top during the last 10 minutes of baking. The cheese adds richness and a golden, bubbly topping.

What should I serve with this?

This casserole is a complete meal on its own, but it pairs beautifully with:

Crusty bread – For sopping up the tomato sauce

The Amish Country Tradition

In Amish and Mennonite communities across Pennsylvania, Ohio, and Indiana, casseroles are a staple of home cooking. They’re practical — one dish, minimal cleanup, and they can feed a large family. They’re economical — using affordable ingredients like ground beef, potatoes, and canned soup. And they’re delicious — simple, honest, and deeply satisfying.

This Tomato Soup Beef Casserole reflects that tradition. No browning the meat, no pre-cooking the potatoes, no complicated steps. Just layer, pour, cover, and bake. It’s the kind of recipe that would be right at home in a Lancaster County church cookbook.

The use of condensed tomato soup is a classic mid-century shortcut that became a pantry staple in Amish and “English” (non-Amish) kitchens alike. It adds tangy flavor and creates a creamy sauce when combined with milk.
