You can prepare Lemon Thyme Butter prior to when you are ready to use it.
Combine all ingredients into a food processor. Pulse until butter is creamy and ingredients are well mixed. Turn out onto parchment paper and form the butter into a cylinder shape. Roll up butter in parchment paper and store in freezer for several months.
Potatoes
Preheat oven to 400 degrees.
Put potatoes into a large bowl. Add the Lawry’s seasoning, pepper, and olive oil. Toss to coat. Spread sliced potatoes out on well greased baking pan. Roast in the oven until golden, about 30 -40 minutes total.
Ten minutes before the potatoes are done roasting, in a small skillet over medium-low heat, melt 2 tablespoons of the herb butter. Add the garlic and cook until slightly browned, 8 to 10 minutes. Be sure butter does not brown. Remove from heat as soon as the garlic is done.
Transfer half of the roasted potatoes to a serving dish and drizzle with half of the herb butter and garlic mixture. Sprinkle with parmesan. Repeat with remaining half of potatoes.
