This Mexican Noodle Casserole (Sopa Seca) Recipe contains fideos, onion, garlic, and tomato.

In most American households, children eat mac and cheese as a quick meal. This was our "boxed mac and cheese" growing up because it uses mostly pantry staples and can be made in under 15 minutes. It is also much healthier than using boxed mac and cheese. 20 years later, I can safely say I still eat this because it is so delicious.

How to make Mexican Noodle Casserole
In a large skillet, start by adding the olive oil on medium heat and wait for it to shimmer. Add the onion for about 5 minutes, until soft and translucent. Toss in the garlic for 1 minute, until fragrant. Pour in the Fideo.
Stir often to avoid burning the noodles for about 2-3 minutes, until toasted. Add the can of diced tomatoes, stir for 1 minute.
Add the chicken broth and wait until the broth boils. Lower heat and add salt and pepper. Keep cooking on low heat for about 12-15 minutes, until the liquid evaporates and the noodles are cooked through.
Garnish with sliced avocado, cilantro, and cotija cheese.
Substitutions
Onion: I used red onion but feel free to use yellow or white onion.
Fideo: You can buy fideo in the ethnic section of your grocery store. If you can't find it, you can also buy angel hair pasta and crush into pieces. It is essentially the same thing.
Broth: You can use chicken broth, vegetable broth or beef broth. When I have neither, I use water and chicken bouillon and it tastes delicious as well.
Tomatoes: Feel free to use tomatoes from a can or fresh tomatoes. If you use fresh tomatoes, throw them in at the same time as the onion to cook them fully.
Toppings: Feel free to top with avocado, cilantro and cotija cheese. I have used feta cheese in the past as well.
Variations
Cooking is a chance to be creative! Have fun with it and feel free to make your own variation.
- Spicy - add chili pepper flakes while cooking to imbue heat into the dish.
- Deluxe - add guacamole, crispy onions or sour cream.
- Kid friendly - add crushed tortilla chips.

Equipment
Equipment can have a big impact on how a recipe turns out. Stone bakeware takes longer to heat up than metal pans, and also retain heat for longer, which could make the recipe more watery, or burnt on the outsides.
I love using my Caraway pots, pans and baking sheets for best quality.
Storage
This will be good in the refrigerator for 2-3 days.
These ingredients don't stand up well to freezing.
Top tip
Make sure the liquid evaporates fully.
