In a skillet over medium-high heat, cook bacon until crisp. Transfer to a paper towel to drain. Remove all but 1 tablespoon of the drippings from the pan.
Add pecans to the pan and cook until fragrant, about 2-3 minutes. Remove from skillet.
Add sliced carrots, 1 tbsp brown sugar, chicken broth, thyme, and salt to the skillet. Cover and bring to a boil. Let simmer stirring occasionally until the carrots are almost tender, about 4-6 minutes.
Uncover and increase the heat. Let simmer for 1 to 2 minutes until liquid is reduced to about 2 tbsp.
Add butter and remaining brown sugar. Toss with the carrots until combined. Cook for about 2-3 more minutes until carrots are completely tender.
Take off the heat, add lemon juice and toss to coat. Season with salt and pepper.
Sprinkle chopped bacon and pecans on top and serve immediately.
