In a 12-inch skillet over medium heat, heat butter until it just begins to brown.
Add flour, salt, and pepper to the pan then brown for 1 additional minute.TIP: It’s important to brown the flour before adding the cream to the pan. The browned butter and flour adds flavor and provides a smooth texture to the creamed peas.
Whisk half ‘n’ half into the flour mixture until smooth.
Add frozen peas and a teaspoon of chopped dill and heat over medium until mixture comes to a simmer and begins to thicken. Stir regularly to ensure the half ‘n’ half does not stick and burn to the bottom of the pan.
Season with additional salt and pepper and garnish with fresh dill and butter, if desired.
