Cast Iron Pork Tenderloin with Vegetables and Bacon

It's Friday night and we are in Massachusetts for December therefore it's all about comfort food in my house. I wanted to use my favorite cast iron pan and make a one pot meal perfect for the 2 of us.  It does take a few steps but I actually served from this pan and the flavors were amazing especially the bacon!

This is a perfect dinner for 2 with maybe some left over for lunch the next day for 1 of you..   Enjoy :)

Chefs Note:  You will find below that I want you to remove the pork at 140 degrees.  You don't want it over cooked and when you continue cooking after adding in the vegetables then let rest a few minutes and slice.  The pork will continue cooking.  



  • Olive oil
  • 4 slices bacon, sliced in 1/2
  • 1 package brussels sprouts (as many as you want)
  • 1 (12 oz) package whole bella mushrooms
  • 1/2 red bell pepper, about 1 cup
  • 1/2 yellow onion, about 1 cup
  • 1 tablespoon unsalted butter
  • 1 pork tenderloin (about 18.4 oz prepackaged)
  • Kosher Salt
  • Freshly ground pepper
  • Extra-virgin olive oil


  1. Preheat oven to 400 degrees. F.  

    Take your large cast iron pan over medium high heat.  Add in about 1 tablespoon of oil then add bacon slices.  Cook each side until crispy.  Remove and set on a paper towel lined plate.  

  2. Add brussels sprouts to the pan over the medium-high temperature.  Let cook for about 5-7 minutes and start to brown.  Add mushrooms in the pan and season lightly with salt and pepper.  Roast in the oven for 15 minutes.  Meanwhile cut up the pepper and onion.  Take the pan out of the oven and move the sprouts and mushrooms to a bowl and cover with foil.  (keep oven on)

  3. Add peppers and onions to the pan and cook for about 10 minutes on medium heat.  Add a pinch of salt and pepper.  Toss in the bowl with the sprouts and mushrooms.

  4. Increase the temperature to medium-high. Season the pork tenderloin with salt and pepper.  Sear pork on all sides (about 3 minutes per side).  Then put in the oven for 10-13 minutes.  The center should read 140 degrees F.  

  5. Carefully take pan out of the oven then toss in the vegetables.  Cut up the bacon and add to the pan as well.  Cook for about 5 minutes.  Drizzle a tablespoon or more of extra-virgin olive oil.  

    Serve and enjoy!
