Ingredients
Instructions
Cook the spaghetti squash
- Step 1
Roast in the oven: Preheat oven to 400F. Cut squash in half lengthwise and place the halves upside down on a lined baking sheet. Cook 40-45 minutes until the skin is fork tender. Let the squash cool and then use a fork to remove all the flesh from the skin into a large mixing bowl. Reduce heat to 375F when the squash is done cooking.
- Step 2
Steam in the Instant Pot: Cut your spaghetti squash in half widthwise, fit it into your Instant Pot on the trivet with one cup of water, and then select Steam on high pressure for 8 minutes with a Natural Pressure Release. Let the squash cool and then use a fork to remove all the flesh from the skin into a large mixing bowl.
Cook the meats and veggies
- Step 3
Place a Dutch oven or deep skillet over Medium heat. When hot, add bacon bits and cook for 8-10 minutes, stirring occasionally, until the bits are browned and crispy to your liking. Remove the bacon bits and place them in a paper towel lined bowl. Carefully remove all but 2 tablespoons of the bacon grease from the pan.
- Step 4
Over medium heat, add the bell pepper, onion, celery, garlic and chicken breast pieces to the pan with the bacon grease. Cook for 10-12 minutes or until the chicken is completely cooked through and all the vegetables are tender.
Put it together
- Step 5
Preheat oven to 375F. To the large mixing bowl with the cooked spaghetti squash strands, add the bacon bits (reserving a few for topping), the chicken and veggie mixture, Ranch dressing, eggs, and 1/4 teaspoon each salt & pepper. Stir until well mixed.
- Step 6
Add the mixture to a greased 9×13 casserole dish. Flatten the mixture out into the casserole dish then sprinkle remaining bacon bits on top.
- Step 7
Bake at 375F for 45-55 minutes, or until the top is golden brown. Broil for the final two minutes for a crisp top. Store leftovers in an airtight sealed container and enjoy within 4 days.
