Ingredients (makes 4 servings)

  • 1/2 cup extra virgin olive oil (120 ml/ 4 fl oz)
  • 2 tbsp fresh lime juice (30 ml)
  • 1 tsp chile powder, or to taste (chipotle for hot, ancho for mild)
  • 1 tsp ground cumin
  • 2 cloves garlic, minced
  • 1 tsp sea salt
  • 1/2 tsp ground black pepper
  • 1/2 medium red onion, sliced (50 g/ 1.8 oz)
  • 1 medium green bell pepper (120 g/ 4.2 oz)
  • 1 medium red bell pepper (120 g/ 4.2 oz)
  • 2 medium yellow and/or orange bell peppers (340 g/ 12 oz)
  • 600 g raw shrimp/prawns, deveined (1.3 lb)
  • Optional: sour cream, lime wedges and fresh cilantro or parsley to serve

Instructions

  1. To make the marinade, juice the lime and place in a small bowl together with the spices (chile powder, cumin, salt and pepper) and olive oil. Whisk to combine — the mixture will thicken.
  2. Peel and slice the onion and slice the bell peppers. Mince the garlic. You can use one green bell pepper plus three other bell peppers (red, yellow and/or orange).
  3. Place the peppers in a bowl and add the red onion and garlic. Pour over half of the marinade. Toss to combine. Keto Sheet Pan Shrimp Fajitas
  4. In another bowl combine the shrimp with the remaining marinade. Place in the fridge for at least 30 minutes or overnight. Keto Sheet Pan Shrimp Fajitas
  5. Remove the peppers from the fridge. Place in a tray together with the marinade and bake at 200 °C/ 400 °F (fan assisted), or 220 °C/ 425 °F (conventional) for 10 minutes, tossing and rotating the tray halfway to ensure even cooking. Keto Sheet Pan Shrimp Fajitas
  6. After 10 minutes, turn on the broiler, add the marinated shrimp and cook on high for another 5 to 8 minutes. (You will have some marinade left from the prawns. Do not pour it into the tray as it would make the meal too watery.)
  7. Remove from the oven and set aside to cool for 5 minutes before serving. Optionally, serve with lime wedges, cilantro (or parsley), sour cream and/or Keto Tortillas. Store in the fridge for up to 3 days. Keto Sheet Pan Shrimp Fajitas

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

What temperature do you set the oven?

Well spotted! See step 5. Once I add the shrimp I just broil it on high (240-250 C).

… but what about the temperature for the peppers and onions?

I fixed that part (see step 5) - it was previously missing.
