PSMF Sheet Pan Recipe

Both Mr. Grumbles and I love fajitas.

It's not every day that we agree on recipes.  He is a wheat-eater and I am not so it can make mealtime sometimes difficult.

Except when it comes to fajitas.

He loves fajitas in a tortilla and I love putting the mixture on a salad to make this a high protein dinner recipe perfect for my protein-sparing modified fasting days! (You can read all about PSMF on this blog post!)

What I don't like about fajitas is the mess it makes on my stovetop.

As careful as I possibly try to be, the oil needed to make the fajitas always seems to get everywhere.

There is a reason why Mr. Grumbles refers to me as Messy Marvin!

But not anymore since finding this AMAZING recipe on America's Test Kitchen! Not only is this recipe super tasty and utterly delicious, but it also comes together in under 30 minutes using only a single sheet pan!

I honestly think that this Sheet Pan Beef Fajita recipe will help to hold our marriage together for years to come! 🙂

What ingredients do you need to make Sheet Pan Steak Fajitas?

• Flank steak - You will need 11/2 pound of flank steak which will be cut into 3 equal sections
• Peppers - Use any colour variation you wish!
• Onion - I like to use a red onion but any onion will work.
• Spices - I like to use a combination of garlic powder, chili powder, salt, black pepper and some sweetener
• Oil - This helps to get a nice "charred" look on the peppers and onions.

Keto Sheet Pan Steak Fajitas Instructions

Are you ready to make this high protein dinner recipe? Let's do this!

Step 1 - Give the veggies a head start!

• Adjust oven rack to lower-middle position and heat oven to 475 degrees. Toss bell peppers, onion, garlic, oil, 1 teaspoon salt, and 1 teaspoon pepper together on rimmed baking sheet and spread into even layer. Roast until vegetables are lightly browned around edges, about 10 minutes.

Step 2 - Get the steak ready

• While the veggies are roasting, combine the chili powder, sweetener, 2 teaspoons salt, and 1 teaspoon pepper in bowl. Cut the steak lengthwise with grain into 3 equal pieces. Pat steaks dry with paper towels, then sprinkle all over with spice mixture.

Step 3 - Get everyone roasting!

• Remove sheet from oven. Using a rubber spatula, push vegetables to 1 half of the sheet. If using, add whole grape tomatoes on top of the veggies. Place steaks on the other half of the sheet, leaving space between steaks. Roast until vegetables are spotty brown and meat registers 135 degrees (for medium), about 8 minutes.

Step 4 - Let rest before devouring

• Remove sheet from oven, transfer steaks to cutting board, and let rest, uncovered, for 5 minutes. Transfer vegetables to serving platter and toss with lime juice.
• Slice steaks thin against grain and transfer to platter with vegetables. Sprinkle with cilantro.

What type of meat can be used?

• rump steak
• skirt steak
• flank steak
• chicken breast or thigh meat
• cod, haddock or any other fish
• shrimp

This recipe instructions are for flank steak.  I like flank steak since it is a leaner meat.  However, feel free to use any of the above choices but make sure that you adjust your baking time accordingly.
