Instructions

  1. Preheat the oven to 350° F (175° C) and if not, using a cast iron skillet for baking, then prepare a 9x13 inch casserole dish by spraying lightly with spray oil.
  2. In a large (cast iron skillet) heat oil and butter over medium heat and saute onions for 5 minutes. Add peppers and saute 2 more minutes, add garlic saute until fragrant, about 1 minute.
  3. Scoot veggies to the side or remove to plate. Brown ground beef until just browned and crumbled, scoot ground beef to the side of the pan and saute sliced (or shredded) zucchini and yellow squash 4-5 minutes until tender. Then add back onions and peppers, stirring to combine.
  4. Reduce heat to medium-low stirring in tomato sauce, tomato paste, Worcestershire sauce, Italian seasoning, salt, pepper mixing until combined. Stir in cream cheese and sour cream, until melted and incorporated into the meat mixture.
  5. May keep in an oven safe skillet if desired or transfer to a 9x13 inch baking dish, sprinkle with shredded cheese and bake, uncovered for 20-25 minutes. Remove from oven and let sit for 10 minutes before serving.
  6. See notes for how to garnish with more crispy zucchini!

  • Add up to 1 ½ cups cooked (and cooled) white or brown rice or other favorite grain; increase jar of spaghetti sauce to full jar)
  • I added 2 ‘fried’ zucchini slices to the top of the casserole as a garnish. I added it after it was fully cooked. All I did was heat some oil in a pan, add the slices and let them sear/pan-fry, flipped, and then topped it off.
