Common Mistakes to Avoid

When making the Instant Pot Stuffed Pepper Casserole recipe, it’s easy to slip up. Here are some common mistakes to watch out for:

Skipping the Browning Step: Skipping the browning of the beef can lead to a less flavorful dish. Always brown your meat first for a richer taste.
Not Measuring Ingredients: Adding too much or too little of an ingredient can throw off the balance of flavors. Use measuring cups and spoons for accuracy.
Ignoring Natural Release: Using a quick release right after cooking can result in unevenly cooked rice. Allow for some natural release time to ensure perfect texture.
Overcrowding the Pot: Trying to fit too much in your Instant Pot can affect cooking times and results. Stick to the recipe amounts for best results.
Neglecting to Stir Before Cooking: Failing to stir the ingredients before sealing can lead to burning at the bottom. Mix everything well before locking the lid.
