Ingredients

  • 1 lb ground italian sausage hot or mild, depending on your personal preference
  • ½ onion diced finely
  • 6 cloves garlic diced finely
  • 8 oz cremini mushrooms cleaned and sliced thin
  • 2 tbsp italian herbs blend
  • 1 bell pepper seeded and diced
  • 1 cup sliced pepperonis whatever thin-sliced pepperoni brand you love
  • ½ cup sliced black olives
  • 2 cups shredded mozzarella
  • 1 cup ricotta cheese
  • 1 cup grated parmesan cheese
  • 1 can diced tomatoes - do not drain

Instructions

  • Preheat oven to 350 degrees Fahrenheit.
  • In a large pan, cook and crumble ground italian sausage on medium high heat.
  • When Italian sausage is browned, remove from pan and set aside. Do not drain or clean out pan.
  • Add onions to pan and let soften and brown, about 5 minutes.
  • Add garlic to pan and cook down until fragrant and lightly browned, another 3-4 minutes on medium-low. Do not let garlic burn.
  • Add peppers and mushrooms to pan and cook to softened and lightly browned.
  • Drain off any excess moisture from vegetables (very important!! I often will squeeze them to get any excess water out of the vegetables.)
  • Prep a 9x9 casserole dish with coconut oil cooking spray (or your favorite way to prep pans - foil, parchment, butter, lard, cooking spray all work just fine.)
  • Layer 1/2 the sausage crumbles onto the bottom of the pan.
  • Add a layer of ricotta, parmesan, and mozzarella (use about 1/3 of each, there will be 3 layers of cheese overall.)
  • Add a layer of 1/2 the vegetables.
  • Layer some (about 1/2) the pepperonis across the casserole.
  • Add a layer of diced tomatoes (and the water they are packed in.)
  • Layer the rest of the meat, then another cheese layer, followed by the rest of the vegetables and tomatoes.
  • Finish the casserole with a top layer of cheese and pepperonis, garnish with olives.
  • Cover casserole with foil and bake for 20 minutes, until casserole is hot and bubbly.
  • Remove foil and cook until cheese is browned, about another 10 minutes.
  • Serve immediately and enjoy.

Notes

To further reduce carbs, you can eliminate the onion and reduce the garlic - as well as adding only 1/2 a diced bell pepper.
I personally think the flavor the vegetables brings is worth the extra carbs, but if you are closely watching macros, reducing the bell pepper, onion, and garlic can eliminate up to 6 carbs per serving.
