How to Make frito pie casserole
1. Preheat the oven to 350°F (175°C).
Set your oven and let it warm up while you gather your ingredients. This ensures a perfectly baked casserole with a bubbly, golden top!
2. Warm the chili in a skillet over medium heat.
Pour in 1 can of chili (with or without beans) and stir occasionally until it's heated through, about 5-7 minutes. The aroma will be irresistible!
3. Layer half of the Fritos in a 9x13 inch baking dish.
Start building your frito pie casserole by evenly spreading 2 cups of Fritos across the bottom, creating a crunchy base that holds all the deliciousness.
4. Add the heated chili on top of the Fritos.
Spoon the warmed chili over the corn chips, covering them completely. This layer adds warmth and flavor that melds beautifully with the crunch below.
5. Sprinkle half of the shredded cheese over the chili.
Use 1 cup of shredded cheddar cheese (or a cheese blend) to create a gooey layer that will melt into perfection as it bakes.
6. Repeat with remaining ingredients.
Layer on the rest of the Fritos followed by the remaining chili and finish with another cup of cheese, ensuring every bite is packed with flavor.
7. Bake in your preheated oven for 20-25 minutes.
Keep an eye on it! You’ll know it’s ready when the cheese is melted and bubbly, creating that delightful golden crust on top.
8. Remove from the oven and let cool for a few minutes.
This brief cooling time allows everything to set slightly, making serving easier and enhancing those tempting layers.
9. Top with sour cream, diced tomatoes, jalapeños, and green onions before serving.
Add 1 cup of sour cream along with fresh or canned diced tomatoes, sliced jalapeños (if using), and sprinkle with ¼ cup chopped green onions for that colorful finishing touch!
Optional: Serve with extra toppings like avocado for added creaminess.
