FAQ

Can I use red lentils instead of regular lentils?

Red lentils cook faster and break down more, so reduce cooking time to 10-15 minutes and expect a softer texture in the final dish.

What if I don't have Cajun seasoning?

Mix paprika, garlic powder, onion powder, oregano, thyme, and a pinch of cayenne pepper as a substitute for similar flavor.

How long will this casserole keep in the refrigerator?

Store covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave or the whole dish in a 300F oven.
