Grocery List

Fresh Produce

  • 1 lb broccolini, with stalks no wider than ½"
  • .25 oz fresh chives
  • .25 oz fresh tarragon
  • 1 garlic cloves
  • 1 lemons

Meat / Poultry / Seafood

  • 4 flat iron steaks, each 6 to 8 oz and about 1" thick

Oil and Spices

  • 1 tsp crushed red pepper flakes
  • .25 cups extra-virgin olive oil
  • .25 tsp freshly ground black pepper
  • 1.5 tsp kosher salt


  • .5 cups unsalted butter



  • ½ cup (1 stick) unsalted butter, softened
  • 1 tablespoon finely chopped fresh tarragon leaves
  • 1 tablespoon finely chopped fresh chives
  • 1 garlic clove, grated or minced
  • ½ teaspoon finely grated lemon zest
  • ½ teaspoon kosher salt

  • 4 flatiron steaks, each 6 to 8 ounces and about 1 inch thick, excess fat and any gristle removed
  • Extra-virgin olive oil
  • Kosher salt
  • Freshly ground black pepper

  • 1 pound broccolini, with stalks no wider than ½ inch
  • 1 teaspoon crushed red pepper flakes


  1. In a small bowl combine the butter ingredients. Scoop the mixture out of the bowl onto a sheet of parchment or waxed paper. Loosely shape the mixture into a log about 1 inch in diameter. Roll the log in the paper and twist the ends in opposite directions to form an even cylinder. Refrigerate for at least 1 hour, or until the butter is chilled.

  2. Lightly brush the steaks on both sides with oil and season evenly with salt and pepper. Allow the steaks to stand at room temperature for 15 to 30 minutes before grilling. In a large bowl of water, submerge the broccolini for 20 to 30 minutes so that they absorb water. This will help them steam a little on the grill.

  3. Prepare the grill for direct and indirect cooking over high heat (450° to 550°F).

  4. Pour off the water from the bowl of broccolini. Lightly drizzle some oil over the broccolini and season with salt and the red pepper flakes. Toss to coat evenly.

  5. Brush the cooking grates clean. Grill the steaks over direct high heat, with the lid closed as much as possible, until cooked to your desired doneness, 6 to 8 minutes for medium rare, turning once or twice (if flare-ups occur, move the steaks temporarily over indirect heat). Remove from the grill and let rest while you grill the broccolini.

  6. Using tongs, lift the broccolini and allow any excess oil to drip back into the bowl. Grill the broccolini over direct high heat, with the lid closed as much as possible, until lightly charred, 3 to 4 minutes, turning occasionally. Finish cooking over indirect high heat for 2 to 3 minutes.

  7. Cut four ½-inch-thick pieces of butter and place one in the center of each steak. Serve warm with the broccolini.

I previously owned a Weber Spirit 700 which I decided to sell prior to a move. My girlfriend and I currently have a Weber Charcoal Kettle. We decided we wanted a gas grill but it needed to have a small footprint because our patio is not large and we wanted to keep the kettle. I started doing some research and quickly settled on the Q300. We really liked the small footprint and fold down trays. I was a bit skeptical about the grate design and the lack of Flavorizer Bars. I quickly learned the grate design is a strength not a weakness. Even without Flavorizer Bars the Q300 flares up less and cooks more evenly than my old Spirit 700 did. So far I have cooked steaks, burgers, chicken breasts, potatoes and pizza. The results have been great. I have three very small concerns. With both burners lit and set to the lowest settings the grill still exceeds 500 degrees. If I want to grill at a temp below 500 degrees I have to shut off the center burner which means indirect cooking. I have not tried using the center burner only. Secondly, I realize this is Weber's low end of gas grills but I think it should have come with a gas tank gauge. Third, I am surprised I usually need to push the starter button three to five times to start the grill. My old Spirit never required more than two pushes and usually started with just one push.

Overall we love this grill and I can honestly say it is better than I expected. It is more than enough grill for a couple that grills for ourselves and occasionally our kids or neighbors. It appears to have Weber's great design and the quality of parts seems very good. I read a few reviews that questioned the quality of the cart but I don't have any issues or concerns.

Highly recommended.
