Creating amazing Rosemary Garlic Mashed Potatoes can be achieved easily by following these steps:

1. Prepare the Potatoes: Peel and cut the russet potatoes into uniform chunks. This ensures they cook evenly.
2. Boil the Potatoes: Place the potato chunks in a large pot and cover them with cold water. Add a generous pinch of salt and bring to a boil over medium-high heat.
3. Cook Until Tender: Once boiling, lower the heat and simmer the potatoes for about 15-20 minutes until they are fork-tender.
4. Sauté Garlic: While the potatoes are cooking, melt the butter in a small pan over medium heat. Add the minced garlic and sauté until fragrant, about 1-2 minutes. Be careful not to let it burn!
5. Drain Potatoes: Once the potatoes are cooked, drain them well in a colander and return them to the pot.
6. Mash the Potatoes: Using a potato masher or a ricer, mash the potatoes until smooth and creamy.
7. Combine Ingredients: Add the sautéed garlic and butter to the mashed potatoes, followed by the milk and chopped rosemary.
8. Season: Mix everything together until combined. Add salt and pepper to taste. Adjust the consistency with more milk if necessary.
9. Heat Through: Place the pot back over low heat, stirring occasionally until everything is heated through.
10. Serve: Spoon the Rosemary Garlic Mashed Potatoes into a serving dish, garnishing with additional rosemary if desired.
