Equipment

  • 1 9 x 13 in casserole dish
  • tin foil

Ingredients
  

  • 1 box rotini pasta (16 oz)
  • 2 cups chicken, shredded *See recipe notes
  • 1 zucchini squash
  • 1 yellow squash
  • 2 roma tomatoes
  • 1 cup ranch dressing
  • ¾ cup pesto
  • 2 cups shredded mozzarella cheese

Instructions
 

Prep Work

  • Preheat the oven to 350 ℉. Fill a large pot with enough water to cook the whole box of pasta and start heating it on high heat.
  • Dice the tomatoes, zucchini, and yellow squash into small, bite size pieces, placing the cut zucchini and squash in a bowl separate from the tomatoes.

Cook

  • Once the water is boiling, cook the pasta according to box instructions.
  • While the pasta is boiling, make the pesto ranch sauce by combining 1 cup of ranch dressing with ¾ cup of pesto in a bowl or liquid measuring cup.
  • Just before the pasta is finished boiling (about a minute or two if you set timers), dump the squash into the water to cook the contents slightly.
  • Once the pasta is finished cooking, pour the contents of the pot into a colander. Then, once the water has drained, put your pasta and squash back in the pot.
  • Quickly add the tomatoes, shredded chicken, pesto ranch sauce, and 1 cup of mozzarella cheese to the pot. Stir until the contents are well mixed so the sauce and vegetables are evenly distributed.

Bake

  • Pour the mixture into a 9 x 13 in baking dish and top with the remaining 1 cup of mozzarella cheese.
  • Cover the dish with tin foil and bake for 15 minutes. Then, remove the foil and bake for an additional 10-15 minutes or until the cheese is bubbly.

Notes

  • I usually just use a can of chicken of whatever size that I have on hand.
  • If you do not love all the squash, the recipe can also be done with broccoli florets instead of yellow squash.
  • I tend to top the casserole with more than just 1 cup of cheese because I really love cheese. If 1 cup seems a little stingy, definitely sprinkle more!
The Vegetable Chopper I Use
If you (like me) hate standing at the counter doing prep work and cutting vegetables, you should get a vegetable chopper. Here's the one I use. They went viral a few years back so I got one, and I don't regret it. It saves so much time and effort, and it's dishwasher safe. SCORE!
