Ingredients

Find the complete ingredient list, with measurements, in the recipe card below.

• Olive Oil + Butter – For sauteeing the onions and garlic.
• Onions + Garlic – These elements add 
• Ground Beef – We use grass-fed lean ground beef, but regular or extra lean will also work.
• Salt + Pepper – A pinch of salt and pepper will bring out the best flavors in your ingredients.
• Tomato Sauce – We use a plain variety and add our own seasonings.
• Crushed Fire-Roasted Tomatoes – This brings a smoky element to the dish. You could also use regular crushed tomatoes.
• Russet Potatoes – Russets keep their shape when the casserole is baked and won’t turn to mush.
• Cheese – Our choice is marble, which has a mixture of mozzarella cheese and cheddar cheese. It melts beautifully on top of the casserole.
• Basil – A sprinkle of basil brings a beautiful pop of color and a burst of fresh flavor.

Equipment

• Large bottomed saucepan or large skillet – It is best to use a deep pot or pan to reduce tomato sauce splatter. It’s easier to wash the pot than the whole stovetop.
• Baking Dish – We recommend an 8×11 or 9×9 casserole dish.
• Foil – This is used to cover the baking dish while the casserole cooks.

Instructions

Scroll to the recipe card at the bottom for the FULL recipe details.

Step 1

Start by warming the butter and oil in the pan over medium heat.

Step 2

Next, add the onions and sweat them down for 3-5 minutes to soften them.

Step 3

Then, add the minced garlic and stir for one minute.

Step 4

Next, add the ground beef and break it up with a wooden spoon. Cook until browned through and no pink remains, stirring occasionally.

Step 5

Then, pour in the tomato sauce and crushed fire-roasted tomatoes. Stir it well to combine everything and bring it to a quick boil.

Reduce the heat and let the ground beef mixture simmer for 10-15 minutes.

Step 6

Meanwhile, grease the baking dish and preheat your oven to 375.

Peel the russet potatoes and slice them into 1/4-inch thick rounds.

Step 7

Next, add an even layer of the sliced potatoes to the bottom of the greased casserole dish.

Step 8

Follow that up with a layer of the cooked ground beef sauce.

Step 9

Repeat that order and then top the mixture evenly with the shredded cheese.

Step 10

Finally, cover the dish with foil and pop it into the preheated oven. Bake for 40 minutes covered, then remove the foil and bake for another 10-15 minutes.

Once it is browned and bubbling, it is ready!

Sprinkle on some fresh chopped basil for flavor, color, and aromatherapy.

I LOVE the clean herbaceous scent of summertime basil.

Substitutions

• Lighten it up by using leaner protein such as ground turkey or ground chicken.
• Use sweet potatoes or fingerlings instead of russets.
• Instead of fresh garlic and onion, garlic powder and onion powder will work in a pinch.
• Substitute freshly chopped oregano instead of basil for a more woodsy flavor.

Recipe Variations

• Give it a southwestern vibe by adding black beans, corn, and some homemade taco seasoning.
• Kick it up a notch with a topping of homemade tater tots.
• For a more creamy sauce, stir in a couple of spoonfuls of cream cheese or sour cream into the sauce after it simmers.

Serving Suggestions

• We love serving this with a simple lettuce salad on the side. If you want to get fancy, try this arugula salad.
• You can make it super hearty with a side of egg noodles, whole grain, or gluten-free pasta. We also serve it with brown rice cooked in broth.
