Ingredients You’ll Need  

This recipe keeps things simple yet flavorful. Here’s what you’ll need:

For the Marinade:

- 1/4 cup olive oil (or avocado oil for a lighter taste)  

- 3 garlic cloves, finely minced (or 1 tsp garlic paste)  

- 2 tbsp fresh rosemary, chopped (substitute with 1 tbsp dried rosemary if needed)  

- 1 tbsp fresh thyme leaves  

- 1 tbsp Dijon mustard  

- 1 tbsp balsamic vinegar  

- 1 tsp honey (optional, for a touch of sweetness)  

- 1 tsp salt  

- 1/2 tsp freshly ground black pepper 

For the Beef Tenderloin:

- 2 lbs beef tenderloin (trimmed and tied if necessary)  

- 1 tbsp butter (or a dairy-free alternative)  

- 1 tbsp olive oil

Optional Toppings and Garnishes:

- Fresh parsley, chopped  

- A sprinkle of flaky sea salt  

Dietary Notes: For gluten-free diners, ensure your Dijon mustard and balsamic vinegar are certified gluten-free. Dairy-free families can substitute the butter with plant-based alternatives.

Step-by-Step Instructions  

Cooking with kids? Make this recipe interactive by letting them help with these fun tasks!  

1. Prepare the Marinade

In a medium bowl, whisk together olive oil, minced garlic, rosemary, thyme, Dijon mustard, balsamic vinegar, honey, salt, and pepper. The mixture should be fragrant and slightly thick.  

Tip for Kids: Let the kids whisk the marinade—it’s a simple yet exciting task that makes them feel involved!  

2. Marinate the Beef

Place the beef tenderloin in a large resealable bag or a shallow dish. Pour the marinade over the beef, ensuring it’s evenly coated. Seal the bag or cover the dish, and refrigerate for at least 30 minutes (or up to 24 hours for maximum flavor).  

Interactive Idea: Ask your kids to “massage” the marinade into the meat (through the bag) to ensure it’s well coated.  

3. Preheat and Prep the Grill

Heat your grill to medium-high. If using a stovetop, heat a cast-iron skillet on medium-high until it’s smoking hot.  

While the grill heats, remove the beef from the fridge and let it sit at room temperature for about 10 minutes. This ensures even cooking.  

4. Sear the Beef  

Brush your grill or skillet with olive oil. Sear the beef tenderloin for about 2-3 minutes per side, ensuring it develops a nice crust.  

Pro Tip: If you’re using a skillet, add butter for an extra layer of richness.  

5. Finish Cooking

Transfer the beef to a cooler part of the grill or reduce the heat on your stovetop to medium. Cook until the internal temperature reaches 135°F for medium-rare (about 10-12 minutes), or your preferred doneness.  

Use a meat thermometer for accuracy, and remember: the beef will continue to cook slightly after being removed from the heat.  

6. Rest and Serve

Let the beef rest for 10 minutes before slicing. This step ensures the juices redistribute for maximum tenderness and flavor.  

Fun Idea for Kids: While the beef rests, let your kids help set the table or sprinkle fresh parsley as a garnish.
