FAQs

How do I make homemade fajita seasoning?

Combine chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, black pepper, and a pinch of cayenne for a simple homemade blend.

Can I use pre-cooked chicken?

Yes, but reduce baking time and add the chicken during the last 15–20 minutes to avoid drying it out.

Can I make this casserole dairy-free?

Absolutely. Omit the cheese or use a dairy-free cheese alternative that melts well.

What type of rice works best?

Long-grain white rice is ideal. Avoid instant rice, which will overcook.

Can I prepare this casserole in advance?

Yes. Assemble the casserole up to a day ahead, refrigerate, and bake when ready.

How do I make this spicier?

Add chopped jalapeños, extra chili powder, or use a hot fajita seasoning.

Is this casserole freezer-friendly?

Yes. Freeze in portions or as a whole dish, then reheat after thawing overnight in the refrigerator.

Can I use brown rice instead?

Yes, but increase the liquid and baking time, as brown rice takes longer to cook.

What other toppings go well with this casserole?

Diced tomatoes, green onions, crushed tortilla chips, or a drizzle of lime juice add great flavor.

Can I cook this in a slow cooker?

While it’s best baked, you can adapt it to a slow cooker using cooked rice and shorter cook times.
