Take a large bowl, fill it with 4 cups of tap water and 3 tablespoons of table salt, and stir till it dissolves. Submerge the chicken breasts and leave them rest for about 45 minutes.
Making the Mashed Potatoes
Peel the potatoes and cut them into chunks. Put them in a large pot and cover them with tap water so the liquid level is at least two fingers above the potatoes. Add a teaspoon of salt, too, and bring to a boil.
Let them simmer for about 20 minutes, depending on how big your pieces are. Check it by poking them with a fork – they are done when it can pass effortlessly.
Take a whole garlic head and cut off the top, revealing the cloves. Drizzle it generously with olive oil and sprinkle with a tad of salt. Wrap it in baking paper or aluminum foil and bake at 350 °F (180 °C) for approximately 20 minutes, until soft.
Peel and dice some shallots along. When the potatoes are ready, drain the water and use the same pot to caramelize the onion. Fry it on a sprinkle of olive oil, until golden brown.
Return the potatoes to the pot, squeeze out baked garlic cloves, season it with salt and freshly ground pepper to taste, and mash. Halfway along, add some sour cream, butter, and milk and continue until you’re satisfied with the consistency.
Preparing the Chicken
In a bowl combine the spices and herbs: salt, ground pepper, paprika, rosemary, parsley, basil, oregano, and dill.
Remove chicken breasts from the wet brine and tap them dry with a paper towel. Thin them out if needed and beat them with a kitchen mallet so they are tenderer. Massage the herbal mixture into the breasts and do it properly – it can never be too much!
Pour some olive oil into the skillet, and heat it on medium. Slowly fry your chicken so it doesn’t burn. The herbs will be darker in color, but that’s okay. Crisp them out from both sides for a few minutes and fry a bit more until the internal temperature is 165 °F (74 °C).
Take them out on the paper towel to absorb the residual fat.
Caramelizing the Lemon
Slice the lemon in half and sprinkle it with some salt. Plus, cover it generously with sugar and put it in the hot skillet flat side down. The sugar will caramelize in a few minutes and reach golden brown color, so that’s the moment to remove it from the stove.
Serving
Take two bowls and serve garlicky mashed potatoes in one and in the other, serve a few baby carrots for additional texture. Arrange the herb-crusted chicken and top it with half of the caramelized lemon. I recommend you drizzle the lemon juice on both chicken and potatoes as it smashes the taste and skyrockets the flavors.
