Steak Fajita Rice Casserole

Pro tips

• Stir the cheesy rice mix with water first to dissolve seasoning evenly before adding protein and vegetables.
• Don't skip sautéing the frozen pepper-onion blend—it removes excess moisture and prevents a watery casserole.
• Drizzle the queso dip over the top just before serving or baking for the creamiest texture; overheating can cause it to separate.
• Use a 9x13-inch casserole dish for even cooking and to prevent overflow.

Substitutions

• Pre-cooked fajita steak → shredded rotisserie chicken or cooked ground beef
• Cheesy Mexican rice mix → plain long-grain rice (1.5 cups uncooked) + 3 cups broth + 1 packet taco seasoning + 1 cup shredded cheddar
• Queso cheese dip → sour cream mixed with shredded cheese or Mexican crema
