Recipe Tips

• Rice: Ensure you use long-grain white rice; brown rice will require longer cooking.
• Cheese: Feel free to mix in Monterey Jack or mozzarella for a milder, gooier texture.
• Vegetables: Frozen vegetables work best, but fresh can be used; adjust cooking time accordingly.
• Make-Ahead: You can prep everything in the slow cooker insert the night before; just refrigerate overnight and cook the next day.

Variations

• Spicy Version: Add 1/2 tsp red pepper flakes or a few dashes of hot sauce.
• Creamier Version: Stir in 1/2 cup sour cream before adding the cheese.
• Vegetarian Version: Replace beef with sautéed mushrooms or lentils and use vegetable broth.
• Grain Swap: Try quinoa or orzo instead of rice for a different texture.

Freezing and Storage

• Storage: Refrigerate leftovers in an airtight container for up to 3–4 days.
• Freezing: Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator and reheat on the stove or in the microwave.

Special Equipment Needed

• Slow cooker (4–6 quart capacity)
• Skillet for browning beef
• Wooden spoon for stirring
• Measuring cups and spoons
