This Vegan Stuffed Pepper Casserole is made of lentils, rice, peppers and non dairy cheese for the flavors of traditional stuffed peppers with less work.

We love cozy, hearty meals like this Vegan Stuffed Pepper Casserole. It has all the flavors of the traditional dish without meat and dairy and you'll need less time to assemble. Traditional stuffed peppers are made with beef. To make our vegan version we use lentils, which are hearty, a great source of protein and full of fiber. Another great thing of this dish is it can be made all in pot if you have an oven safe skillet or dutch oven.

How to make Stuffed Pepper Casserole
Stuffed Pepper Casserole is simple to make with little hands on time needed. If you are using dried lentils prepare ahead of time to keep cooking time down. Prep all ingredients before getting started as this recipe moves quickly. Start by removing seeds from peppers and chop into bite size pieces. Measure out spices, paste, broth etc. having everything ready to add when needed before you heat the pan.

Heat oil over medium heat in a large skillet. Add peppers and sauté for 5-10 minutes until they begin to soften. Add spices, tomatoes and paste, cook for 1 minute longer.

Add lentils and broth stirring to incorporate.

Add rice to skillet and stir to incorporate. Transfer mixture to a 9x13 oven safe dish, if skillet is not oven safe.

Top with non dairy cheese and cover with foil or lid. Bake at 375 degrees farenheight for 50 minutes. Remove foil and broil for 5 minutes to brown cheese, if desired.
Top Tip
Wash the rice. This helps to remove dirt and excess starch that can make the rice sticky. Washing the rice will yield a fluffier texture after cooking.
Equipment
An oven safe skillet makes this dish super easy to prepare without dirtying up excessive dishes. If you don't have an oven safe skillet you can transfer the mixture to a 9x13 casserole dish.
Storage
Store leftover casserole in an air tight container in the refrigerator. Good for 3-4 days.
