The sharp cheddar is always my favorite part Melty cheesy bubbly edges remind me of my grandmother’s weekend casseroles where everyone raced for the crispy corners The kids insist on extra cheese every time and it turns even plain rice into something special

Storage Tips

Keep leftovers in an airtight container in the fridge up to four days For longer storage freeze in portions or as a whole casserole without toppings for up to two months Thaw overnight in the fridge before reheating Heat gently in the oven or microwave and stir in a splash of chicken broth to keep things moist

Ingredient Substitutions

Use any cooked protein you have on hand Leftover turkey ground beef or even tofu will work If you cannot find Knorr Taco Rice try any Mexican style rice blend Add red bell peppers or a handful of spinach to sneak in more veggies Monterey jack or colby work well if you skip pepper jack

Serving Suggestions

Top with sour cream fresh cilantro avocado slices or crushed tortilla chips Pair it with a simple green salad for freshness If you are feeding a bigger group serve with extra hot sauce or salsa on the side I love adding a side of sautéed peppers and onions for color
