The Wonderful Ingredients
Crust:
- 2 cups all-purpose flour
I love using all-purpose flour for the crust because it’s so versatile, it gives the casserole that perfectly flaky texture. If you’re short on supplies, you can use whole wheat flour, but just note that the texture will be a little denser. - 2 tsp baking powder
This is essential for a light and fluffy crust. If you’re out of baking powder, a mixture of 1 cup cream of tartar and 1/2 teaspoon baking soda can do the trick. - 1/2 tsp salt
A couple pinches of salt really brings out all the flavors in this dish! If you’re watching your sodium intake, you can reduce this a bit or even use a salt substitute. - 1/2 cup unsalted butter (cold and cubed)
Butter is going to give you the best flavor and texture for this recipe. I prefer unsalted butter so that I can control the sodium level myself. You can substitute plant-based butter for a dairy-free version. - 3/4 cup whole milk
Whole milk adds richness to the crust. You can use almond milk or any plant milk if you need a dairy-free option. Just make sure it’s unflavored!
Filling:
- 1 lb ground beef
Ground beef is pure comfort food! You could swap it out for ground turkey or chicken if you want leaner options. Some people even use black beans for a vegetarian spin! - 1 medium yellow onion (diced)
Onions add that wonderful aroma and sweetness. You can go for white or red onions if that’s what you have. The sweeter the onion, the better! - 1 green bell pepper (diced)
This adds some crunch and color. You could also use red or yellow bell peppers for a little sweetness. Plus, they just look amazing! - 1 packet (1 oz) taco seasoning
Who doesn’t love taco seasoning? It adds a burst of flavor that brings everything together. Feel free to make your own mix with cumin, chili powder, and garlic powder if you’re feeling adventurous! - 1/2 cup water
This helps make the filling nice and saucy. You can also use beef or chicken broth for extra flavor. - 1 can (10 oz) diced tomatoes with green chilies (drained)
These guys are key—they add moisture and flavor! But you can use plain diced tomatoes if you prefer, or even fire-roasted ones for a smoky twist. - 1/2 cup sour cream
This adds a creamy goodness you’ll love! If you want to go lower-calorie, plain yogurt can substitute beautifully. - 1/2 cup mayonnaise
It may sound odd, but trust me, it adds creaminess that makes this casserole even more comforting. You could skip it if you’re not a mayo fan or use a mash of avocado instead. - 2 cups shredded cheddar cheese (divided)
Cheese=flavor! I like to use a good sharp cheddar for that robust taste. You could sub it with mozzarella or a dairy-free alternative if needed. - 1 small tomato (sliced)
Fresh tomatoes on top not only look pretty but also add a fresh kick to the dish. If you have any other veggies lying around, toss them on to mix it up! - 1/2 tsp black pepper
A little pepper goes a long way in rounding out the flavor. - 1/2 tsp garlic powder
Garlic is life. You can also add fresh minced garlic when sautéing the onions for even more flavor!
Let’s Get Cooking!
Preheat and Prep
First things first, preheat your oven to 375°F (190°C). You’ll want to lightly grease a 9×13-inch baking dish trust me, no one wants a stuck casserole!
Make the Crust
- In a large bowl, combine the flour, baking powder, and salt. Toss in that cold butter (it’s key for keeping it flaky) and cut it in until the mixture looks crumbly. Usually, I use a pastry cutter for this, but those fingertips work just fine too!
- Stir in the milk until a soft dough forms. It should come together pretty quickly, don’t worry if it’s not perfect, it’s going to bake beautifully!
- Press the dough evenly into the bottom of your greased baking dish. You can use your hands or the back of a spoon.
Cook the Beef Mixture
- In a large skillet over medium heat, brown the ground beef, it should take about 5-7 minutes. You want it perfectly browned and crumbly, just like your favorite taco meat.
- Toss in the onion and bell pepper, cooking until softened (around 5 minutes). The smell oh my word, it’s heavenly!
- Add in the taco seasoning and water; let it simmer for about 2-3 minutes until thickened. This is the time to scrape the yummy bits off the bottom of the pan!
- Mix in the drained diced tomatoes with green chilies. Remove from heat and set aside.
Prepare the Creamy Layer
- In a medium bowl, combine sour cream, mayonnaise, 1 cup of shredded cheese, black pepper, and garlic powder. Stir until combined. It should be creamy and luscious seriously, you might find yourself sneaking a taste.
Assemble the Casserole
- Spread the cooked beef mixture evenly over the crust. Be sure to get all those goodies out of the skillet!
- Dollop and gently spread the sour cream mixture over the beef. Try not to mix it too much; you want layers here!
- Sprinkle the remaining cheddar cheese on top, and arrange the tomato slices over all that cheesy goodness. This step is all about presentation, folks!
Bake to Perfection
- Place in the preheated oven and bake for about 35–40 minutes, until the top is golden and bubbly. That’s the moment we live for, isn’t it? Your kitchen will smell like a fiesta!
- Allow the casserole to rest for about 5 minutes before slicing. Serve warm and watch your family dig in!

- Freezer-friendly: Yes! This casserole freezes beautifully. Just tightly wrap it before baking, and it’ll last in the freezer for up to 3 months. When ready to eat, thaw in the fridge overnight, then bake as directed.
