  • Prep-time: / Ready In:
  • Makes one 13×9-inch casserole

Whole wheat pasta, black beans, and Tex-Mex seasonings make this spaghetti casserole a true crowd-pleaser. Sweet potato puree lends its silky texture to the creamy, chile-infused sauce so every bite is packed full of savory flavors. A hearty jumble of zucchini, bell pepper, corn, and tomatoes bring bursts of fresh produce to balance out the smoky profile and load your plate up with nutrient-dense veggies. Top each serving with fresh scallions and cilantro, and you’ve got a comforting meal that will be gobbled up by kids and adults alike.

Tip: If you can’t find canned sweet potato puree, bake, peel, and mash enough sweet potatoes to make 1½ cups.

I did not have ancho chili seasoning so used chili seasoning.. not sure if it makes a great difference but I needed more flavor. The hubby really liked it.. I did precook veggies as another suggested. Overall good base

The mixed vegetables did not cook completely while baking, especially the onions. I think this would taste better if they had been sautéed before adding them to the pasta

I agree. Why can’t we add the recipe to our Meal Plan subscription?

This sounds delicious. What can you use in place of the cashew butter? No nuts or tofu please.

You could try tahini. It’s made from sesame seeds. Or a white bean or chickpea hummus would work. Coconut is not part of the tree nut or peanut family, so coconut butter is a substitute for nut butter.
