*Post updated with new photos and copy 06/2019

This Unstuffed Pepper Skillet was one of the first recipes I ever put up on my blog! I decided it needed a bit of a makeover, so I re-photographed it recently.

When I first went gluten free, I was looking for easy meals to throw together using one pan or one skillet. I love stuffed peppers, but they can be a lot of work. This dish has all of the flavors without any of the fuss- no blanching or baking the peppers! And it’s totally gluten and dairy free. You can definitely add cheese if you tolerate dairy!

I also love to add fresh basil.

I cooked up this meal in my Lodge Cast Iron 12″ Skillet – I seriously use this for everything!

What ingredients do I need to make this Whole30 Unstuffed Pepper Skillet?

  • Ground beef – I get my grass-fed, grass-finished organic ground beef delivered from Butcher Box!
  • 2 bell peppers, any color
  • 1/2 onion
  • Rao’s marinara sauce (24 oz total – any brand will work, just check to make sure it’s sugar free for Whole30!)
  • Cauliflower rice – I prefer frozen vs. fresh. It has a better texture
  • Nutritional yeast- I get this at Trader Joe’s. It gives dishes a “cheesy” flavor without the dairy. It is basically inactive yeast, and is Whole30, gluten free, paleo, etc.
  • Coconut aminos – this gives this dish a hint of sweetness.

You can also use regular rice in place of cauliflower rice. You will need to cook the rice first, and then add it in with everything in the skillet, and stir to combine. This will still be gluten free, but not paleo or Whole30 since grains are not allowed.

Can you freeze this dish?

Yes, it freezes well!

Can you use other types of meat?

Yes! Ground pork, turkey, or chicken would also be great. Or sausage!
