I hope you all had a wonderful Thanksgiving! I can’t believe it’s December, I know it’s going to fly by. Before everything gets too crazy with recipes for Christmas cookies, brunch casseroles and more ham recipes than you’ll ever need, I wanted to share the recipe for this Southwest Lentil and Brown Rice Casserole.

After all the rich Thanksgiving food and leftovers we had over the last few days, I thought this vegetarian protein and fiber filled dinner would do us all some good. Time to get the body back in check before we eat no less than 100 Christmas cookies.

Aside from how delicious this casserole tastes, the next best thing is how easy it is to make. Except for sautéing onions and garlic, everything else goes into the casserole dish uncooked. Minimal effort on your end with maximum flavor results.

  • Yellow onion
  • Garlic
  • Green chiles or poblano peppers
  • Brown or green lentils
  • Brown rice (long grain or basmati)
  • Fire roasted tomatoes
  • Chili powder, cumin, oregano, smoked paprika
  • Red enchilada sauce
  • Colby Jack, Monterey Jack or cheddar cheese
  • Avocado, tomatoes and cilantro for toppings (optional)

You probably noticed there’s no meat in this casserole and honestly, I need a little break from it after all the turkey. Even without the meat there’s still plenty of protein. A half cup of cooked lentils has 12 grams of protein and 4 grams of fiber. Combine that with a little more protein and fiber from the brown rice and you have yourself a hearty meatless meal.

For this recipe I used . I love Pacific’s broths because they actually have flavor unlike other brands and I appreciate the simple, real, organic ingredients that are used to make them. No fillers, gums, yeasts, GMOs or MSG. It’s basically what you would use if you were making your own homemade broth.

I used it in this  that I made last month and it was delicious. If you aren’t tired of pumpkin, I highly recommend adding it as a side dish to your Christmas dinner menu.

Absolutely! The only change you will make to the recipe will be to omit the cheese on top. If you’d like feel free to add your favorite shredded vegan cheese instead.


I often get questions about how spicy my Southwest and Mexican recipes are. It can be a difficult question to answer because the amount of spice we can tolerate is different for everybody. Personally I like my food on the spicy, but not so spicy that I can’t taste any of the other ingredients or flavors.

If you like spicy I recommend using a medium heat red enchilada sauce and mild or hot green chiles. You can also add spice or remove spice by using a hot or mild chili powder. If you want the casserole to have mild heat, use mild enchilada sauce and either mild green chiles or a bell pepper.

Before serving, top the Lentil and Brown Rice Casserole with diced tomatoes, avocado and cilantro. A squeeze of fresh lime juice is also a nice finishing touch.

Southwest Lentil and Brown Rice Casserole


yield: 6 SERVINGS
prep time: 10 MINUTES
cook time: 2 HOURS
total time: 2 HOURS 10 MINUTES


  • 2 teaspoons olive oil
  • 3/4 cup diced onion
  • 3 cloves of garlic, grated or minced
  • 4 ounces canned diced green chiles or 3 roasted and diced poblano peppers
  • 3/4 cup dry brown or green lentils
  • 3/4 cup uncooked long grain brown rice
  • 1 1/2 cups red enchilada sauce
  • 14.5 ounce can fire roasted tomatoes, undrained
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon oregano
  • 1/2 teaspoon smoked paprika
  • Kosher salt and fresh ground black pepper to taste (I used approximately 3/4 teaspoon kosher salt)
  • 1 cup shredded sharp cheddar or Colby Jack cheese


  1. Preheat oven to 375 degrees and spray the bottom of a 9×13 ceramic or glass baking dish with cooking spray.
  2. Sauté the onion and poblanos (if not using poblanos just the onion) in the olive oil for 2-3 minutes in a medium sized skillet. When the onions are soft stir in the garlic and sauté another 30 seconds. Pour the mixture into the prepared baking dish.
  3. Add in the remaining ingredients, except the cheese, and stir together until well combined. Cover with aluminum foil and bake for 100-110 minutes, stirring everything once during the baking time.
  4. Remove the foil and sprinkle on the cheese. Bake another 15 minutes or until the cheese is melted. Remove the casserole from the oven and let it rest for 10 minutes before serving.
  5. Garnish with chopped tomatoes, avocado and cilantro.
