Poblano and Turkey Sausage Casserole

4 from 1 vote

This casserole isn't only healthy—it's also convenient.

Most casseroles include unhealthy fats from meat and cheese. Not this one! This roasted poblano and sausage casserole uses low-fat cheese, Greek yogurt, and lean meat. You’ll get all the protein you’d get from any other meaty casserole, but without the unhealthy fats. Even the topping provides nutrition, since it uses avocados and tomatoes. Avocados are nutritional powerhouses. They’re packed with omega-3 fatty acids, potassium, fiber, and vitamin K. Tomatoes are also full of nutrients, especially vitamin C.

This casserole isn’t only healthy—it’s also convenient. It freezes well, so you can make extras to keep on hand for busy nights. That way, you can come home from a long, hard day and not have to worry about cooking. You’ll have a hearty meal all ready for you!

  1. I’m so thrilled I found your website. The nutrition helps so much and the recipes are so different and delicious.Certainly not the ordinary Healthy living website.
    I wish there was a way to send the recipes other than printing them.
    Thank you so much.

  2. Thanks for the recipe. I love peppers and can’t wait to make this casserole. Is the Tomato Avocado topping included in the 9 SP per serving? Thank you again. -Katy

  3. Could you substitute cauliflower for the hashbrowns? Drain them very well of course, maybe a healthy option?

    1. Hi, Sarah. That should work out well as a substitute. Let us know what you think if you try the recipe with cauliflower. Thank you!

  4. Can you assemble this the evening before? Also, I love the idea of cauliflower in a previous comment. I wonder how it worked out?

    1. Hi, Sheila. Yes, you can prepare this the evening before. This recipe also freezes well after cooking so you can fix it, then reheat.
