Bring on the comfort food!

One of my favorite things about this meal is just how simple and comforting it can be. To start, you will need to gather oil, sausage, onions, red peppers, garlic, rosemary, thyme, stock, tomato puree, mushrooms, and lentils.

Replacing ingredients in this dish is not hard though, and can be done when necessary. You can substitute the sausage with your favorite chorizo or vegetarian alternative. You can also change the veggies for things like corn, asparagus, and squash. As for the spices, try using basil, dill, or marjoram. You can also substitute the tomato purée with crushed or stewed tomatoes. Finally, the lentils are a big part of this casserole, but you can switch it up with quinoa or chickpeas.

Cooking should only take a few minutes, but make sure to start with the sausage. You can also add the vegetables slowly and the stock and tomatoes towards the end. I suggest you allow the mix to simmer so it thickens and the sausage cooks through.

Allow for your casserole to cool down completely. For a change, try adding some cheese on top and baking it all for a few minutes. This will add crunch and flavor!

Freezing and Unfreezing the Sausage Casserole

Once cool, you can portion out your casserole into freezer bags or airtight containers. Label them appropriately and make sure they stand upright.

To use your frozen casserole, add it to a baking dish and bake at 365 degrees F for at least 45 minutes. Check midway through to make sure things are defrosting evenly. If you have the time, place your frozen meal in the fridge overnight and heat on the stove over medium heat.

Serving Suggestion

Enjoy this yummy freezer-friendly sausage casserole any time! You can serve it with garlic mashed potatoes, or butter noodles.
