Common ingredients include:

  • Minced garlic
  • Dijon mustard
  • Lemon juice and zest
  • Fresh parsley
  • Chives or green onions
  • Red pepper flakes
  • Paprika

The exact composition can vary, but these elements create a balanced blend of savory, tangy, and slightly spicy flavors.

Culinary Uses

  1. A spread for bread or rolls
  2. A topping for grilled meats like steak or chicken
  3. A flavoring for roasted or grilled vegetables

  • 2 cloves minced garlic
  • 1 tablespoon lemon zest
  • 1 tablespoon fresh lemon juice
  • 1/4 teaspoon cayenne pepper
  • 1/4 teaspoon crushed red pepper flakes
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon kosher salt
  • 2 tablespoons chopped fresh herbs (parsley, chives, or thyme)

Adjust measurements to taste, especially for heat and salt levels. Fresh ingredients enhance the flavor profile significantly.

Step-by-Step Instructions


  1. Soften the butter at room temperature for 30 minutes.



  2. In a mixing bowl, combine softened butter with minced garlic, lemon zest, and lemon juice.



  3. Add cayenne pepper, crushed red pepper flakes, black pepper, and kosher salt.



  4. Mix in chopped fresh herbs.



  5. Use a spatula or electric mixer to blend ingredients until evenly distributed.



  6. Shape the butter mixture into a log using plastic wrap or parchment paper.



  7. Refrigerate for at least 2 hours to allow flavors to meld and butter to firm up.


Storage and Shelf-life

Properly stored cowboy butter maintains its quality for up to two weeks. Keep it in an airtight container or wrapped tightly in plastic wrap or parchment paper in the refrigerator. For longer storage, freeze the butter log for up to 3 months.

To use, slice off desired amount and return remainder to storage. Thaw frozen cowboy butter in the refrigerator overnight before use. Bring to room temperature for 15-20 minutes before spreading on grilled zucchini or other dishes.

Selecting and Preparing Zucchini

Choosing the right zucchini and preparing it properly are crucial steps for creating delicious grilled zucchini. These steps ensure optimal flavor and texture in the final dish.

Choosing the Best Zucchini

Select firm, smooth-skinned zucchini with vibrant dark green color. Aim for medium-sized zucchini, about 6-8 inches long and 1-2 inches in diameter. These are ideal for grilling as they’re tender but not overly seedy.

Avoid zucchini with soft spots, blemishes, or wrinkled skin. Smaller zucchini tend to be sweeter and have fewer seeds. Larger ones can be tougher and more watery.

For a low-carb diet option, zucchini is an excellent choice. It’s versatile and can be used as a pasta substitute when made into zucchini noodles with a spiralizer.

Prepping Zucchini for Grilling

Wash zucchini thoroughly under cool running water. Pat dry with paper towels. Trim off both ends.

For grilling, slice zucchini lengthwise into 1/2-inch thick planks. This thickness allows for nice grill marks while maintaining a crisp-tender texture.

Brush the zucchini slices with olive oil. This helps prevent sticking and promotes even browning. Season with salt and pepper.

For added flavor, marinate zucchini in a mixture of olive oil, balsamic vinegar, and garlic for 15-30 minutes before grilling. Don’t marinate longer, as the zucchini can become soggy.

Grilling Techniques

Mastering the art of grilling zucchini requires proper setup and technique. The right approach enhances flavor and texture while preventing common pitfalls like overcooking or sticking.

Setting Up the Grill

Preheat the grill to medium-high heat, around 400°F to 450°F. Clean the grates thoroughly and oil them to prevent sticking. For gas grills, turn on all burners during preheating, then adjust for direct and indirect heat zones.

Create a two-zone fire on charcoal grills. This allows for both high-heat searing and gentler cooking. Arrange coals on one side for direct heat and leave the other side empty for indirect heat.

Use long-handled tools to safely manage food on the hot grill. Keep a spray bottle of water nearby to manage flare-ups quickly.

Grilling for Optimal Flavor

Slice zucchini into 1/4-inch thick planks or rounds for even cooking. Brush with olive oil and season with salt and pepper or a dry rub before grilling.

Place zucchini slices directly over medium-high heat. Grill for 3-4 minutes per side until grill marks appear and the zucchini is tender but not mushy.

For added flavor, baste with cowboy butter mixture during the last minute of grilling. This infuses the zucchini with rich, savory notes.

Avoid moving the zucchini too frequently. Allow each side to develop a nice char before flipping. Use tongs to handle the slices gently, preserving their shape and grill marks.
