Gluten-Free Taco Rice Casserole

A crowd-pleaser if there ever was one, this Gluten-Free Taco Rice Casserole is hearty, filling, and loaded with flavour. It’s the perfect weeknight dinner or freezer meal for busy families and it happens to be naturally gluten-free, too.

This cheesy taco casserole is made with white rice, seasoned ground beef, black beans, corn, and chopped tomatoes then all mixed together with taco seasoning and optionally topped with a generous sprinkle of cheese. It’s a great dish to prep in advance, and even better to freeze for a future dinner when time is tight and tummies are rumbling!

Perfect for Meal Prep and Freezer Stocking

This casserole was one of the lifesavers I made while preparing for the birth of our babies. I had a whole freezer stash of easy meals ready to go, and this taco rice bake was hands down one of the most comforting and filling meals to have on standby.

Even with a newborn in my arms, I could pop this in the oven and have dinner sorted without any fuss. Whether you’re prepping for a new baby, a busy season, or just want to get ahead, this recipe is a must.

How to Freeze Taco Rice Casserole

Here’s how to store it properly:

1. Let the casserole cool to room temperature after assembly or baking.
2. Transfer to a freezer-safe container or tray.
3. Wrap tightly with cling film and foil, or use an airtight lid.
4. Label with the date and freeze for up to 3–4 months.

To Defrost:
Transfer to the fridge and allow to defrost overnight (at least 12 hours). Then bake at 180°C for about 20–25 minutes or until piping hot throughout.

Quick, Easy & Customisable

Making this Gluten-Free Taco Rice Casserole couldn’t be easier. First, cook your white rice. While that’s cooking, brown your beef with tinned tomatoes, sweetcorn, black beans (or kidney beans), and a packet of gluten-free taco seasoning. Mix it all together in a large bowl or directly in your baking dish, top with cheese if desired, and bake until bubbly.

You can easily make this dairy-free by skipping the cheese or using a dairy-free alternative. Want extra veg? Toss in some chopped peppers or courgettes.
