Casserole Ingredients and Variations

PROTEIN: Cooked and shredded chicken breast makes this recipe a timesaver! Leftover ground beef or pork, even turkey will do a well. And bacon makes everything taste better!

VEGGIES: Broccoli and cauliflower give this dish a colorful texture, but you can use other low-carb veggies like zucchini, brussels sprouts, green beans, mushrooms, peas, spinach, or bell peppers.

SAUCE: All great sauces start with heavy cream. Add chicken broth, garlic, cream cheese, and some seasonings. Mix up the flavors and stir in some Southwest Seasoning.

  1. I have lost a ton of weight and hubby has too and have many of your recipes. Thanks for sharing! Sometimes I wonder where we have been the last 50 years!

  2. 4 stars
    I would have given a 5 stars, but after making the sauce, I realized the 1\4 c of chicken broth and also the heavy cream was not enough. I added 1\2 cup more of each. Which made it almost enough. (Next time I will increase again) Plus a little salt to taste is needed. A friend suggested maybe celery salt instead. But overall my husband and granddaughter enjoyed it. I will make it again.

  3. 3 stars
    Made this tonight. It was good but not very much sauce or cheese on top. The flavour was somewhat bland.
    If I were to make it again I would add some seasoning, double the sauce portion and omit the bacon.

    As an aside there was nothing in the instructions about what to do with the bacon once it was cooked. I assumed it was added to the chicken/vegetable mix.
