Ingredients

Here’s what you’ll need to create these delightful Keto Grilled Halloumi & Cherry Tomato Skewers with Basil Oil. Fresh, quality ingredients are key to the vibrant flavors of this dish.

  • For the Skewers:
    • 16 oz (450g) halloumi cheese, drained and cut into 1-inch cubes
    • 1 pint (about 2 cups) cherry tomatoes, washed
    • 1 tablespoon olive oil (for brushing)
    • Salt and freshly ground black pepper to taste
    • 8-10 wooden or metal skewers (if using wooden, soak in water for 30 minutes)
  • For the Basil Oil:
    • 1 cup fresh basil leaves, packed
    • 1/2 cup extra virgin olive oil
    • 1 clove garlic, roughly chopped
    • 1 tablespoon lemon juice
    • Pinch of salt

Step-by-Step Instructions

  1. Prepare the Basil Oil: In a small food processor or blender, combine the fresh basil leaves, extra virgin olive oil, chopped garlic, and lemon juice. Blend until smooth and vibrant green. Season with a pinch of salt. Set aside.
  2. Prepare the Halloumi and Tomatoes: If using wooden skewers, soak them in water for at least 30 minutes to prevent burning. Drain the halloumi cheese and pat it dry with paper towels. Cut the halloumi into 1-inch cubes. Wash the cherry tomatoes.
  3. Assemble the Skewers: Thread the halloumi cubes and cherry tomatoes alternately onto the prepared skewers. Aim for 3-4 pieces of halloumi and 3-4 tomatoes per skewer, depending on their size.
  4. Season and Preheat: Lightly brush the assembled skewers with 1 tablespoon of olive oil. Season generously with salt and freshly ground black pepper. Preheat your grill or grill pan to medium-high heat.
  5. Grill the Skewers: Place the skewers on the preheated grill. Cook for 2-3 minutes per side, rotating frequently, until the halloumi is golden brown and slightly charred, and the tomatoes are softened. The cheese should be warm and slightly gooey inside.
  6. Serve: Carefully remove the skewers from the grill. Arrange them on a serving platter and generously drizzle with the prepared basil oil. Serve immediately and enjoy the burst of fresh flavors.

Pro Tips for Success

  • Pat Halloumi Dry: Pat halloumi thoroughly dry before cutting and grilling. This removes excess moisture, ensuring a perfect golden-brown crust and preventing sticking.
  • Don’t Overcrowd the Grill: Give skewers ample space. Overcrowding lowers temperature, leading to steaming instead of grilling, preventing that desirable char and crisp exterior.
  • Use Fresh, Quality Basil: The basil oil is crucial. Fresh, vibrant basil and good quality extra virgin olive oil make a significant difference in the dish’s final taste and aroma.
  • Soak Wooden Skewers: Soak wooden skewers in water for at least 30 minutes before threading. This prevents them from burning on the grill, ensuring even cooking without splintering.

Variations & Substitutions

  • Spicy Kick: Add red pepper flakes to your basil oil or blend in a finely chopped deseeded jalapeño for heat.
  • Herb Swaps: Experiment with other fresh herbs for the oil, like a mix of parsley and mint for a Mediterranean twist, or cilantro for an Asian profile.
  • Vegetable Additions: Incorporate other keto-friendly vegetables like zucchini slices, bell pepper chunks, or small mushrooms. They grill beautifully alongside.
  • Higher Protein: For extra protein, add pre-cooked chicken breast cubes or shrimp to the skewers. Adjust grilling time for shrimp.
  • Dairy-Free Option: Use firm tofu or a plant-based halloumi substitute. Ensure it’s pressed well and marinated for flavor before grilling.

Serving Suggestions

These skewers are incredibly versatile. Enjoy them as a light lunch or dinner, especially in warmer weather. Pair with a crisp green salad for a complete meal, or serve as an appetizer at a barbecue. For a more substantial keto meal, try them with grilled asparagus or a creamy avocado salad. Best enjoyed fresh off the grill.

Storage & Reheating

Store leftover skewers in an airtight container in the refrigerator for up to 2-3 days. While best fresh, you can gently reheat them. Place on a baking sheet and warm in an oven preheated to 300°F (150°C) for 5-7 minutes, or until heated through. Avoid overcooking, as halloumi can become rubbery. Basil oil stores separately for up to a week.

Frequently Asked Questions

Can I make the basil oil ahead of time?

Yes, the basil oil can be prepared up to 3-4 days in advance. Store it in an airtight container in the refrigerator, making meal prep even quicker.

What if I don’t have a grill?

No grill? No problem! Use a grill pan on your stovetop or bake them in the oven. For baking, preheat to 400°F (200°C) and bake for 15-20 minutes, flipping halfway, until golden.

Can I use different types of tomatoes?

Cherry tomatoes are ideal due to their size and sweetness. Larger tomatoes can become watery. If substituting, use grape tomatoes, which are similar in size and texture for best results.
