What Is Mexican Ground Beef Casserole?
This dish is a stovetop beef and rice casserole inspired by classic Tex‑Mex flavours. Instead of baking in the oven, everything simmers together in one pot until the rice is tender and infused with spice. The final texture is creamy and spoonable, similar to a risotto — but with the bold flavours of tacos and enchiladas.
Ingredients You’ll Need
This recipe uses simple, easy-to-find ingredients:
- Ground beef (beef mince)
- Onion and garlic
- Long‑grain white rice
- Chicken broth
- Tomato paste
- Bell pepper (capsicum)
- Corn kernels
- Black beans
- Green onions
- Shredded melting cheese
Mexican Spice Mix
A homemade blend of cumin, coriander, oregano, paprika, onion powder, cayenne, and salt gives the casserole its signature flavour. Adjust the cayenne to suit your heat preference.
How to Make Mexican Ground Beef Casserole
- Brown the beef – Sauté onion and garlic, then cook the ground beef until no longer pink.
- Build flavour – Add the Mexican spices and cook briefly to bloom the spices.
- Add rice & liquid – Stir in tomato paste, broth, rice, vegetables, corn, and beans.
- Simmer – Cover and cook until the rice is tender and has absorbed the flavours.
- Finish with cheese – Stir in half the cheese, then sprinkle the rest on top and let it melt.
That’s it — one pot, big flavour, dinner done.
