30-Minute Creamy Pesto Mashed Potatoes with Garlic
Silky mashed potatoes infused with basil pesto and garlic, finished with coconut milk or cream for richness. The pesto brings herbaceous brightness to earthy potatoes, making this a vibrant side dish that works year-round. Serve alongside roasted chicken, grilled fish, or vegetables for weeknight dinners or holiday tables. This version skips heavy cream in favor of paleo-friendly coconut oil or tallow, keeping it adaptable to various dietary preferences while maintaining luxurious texture.

Tips
Cube potatoes before boiling to reduce cooking time and simplify mashing. Aim for 1-2 inch pieces.
Add liquid gradually while mashing. Start with half the coconut milk, then adjust to reach your preferred consistency without making them gluey.
Warm the pesto before folding it in if chilled, so it distributes evenly and blends smoothly with warm potatoes.
Good to Know
Refrigerate in airtight container up to 4 days. Reheat gently on stovetop with splash of milk, stirring frequently to prevent sticking.
Prepare through mashing step, cover, and chill. Warm and fold in pesto just before serving to preserve basil color and fresh flavor.
Serve hot alongside roasted or grilled proteins. Pairs well with vegetables, salads, or grain bowls. Works for weeknight dinners, holiday sides, or meal prep.
Common Mistakes
Over-mash potatoes to avoid gluey texture; stop when small lumps remain and liquid is incorporated
Add pesto in stages to avoid overwhelming other flavors; taste as you go

FAQ
Can I make this ahead for a dinner party?
Yes. Boil and mash potatoes up to one day ahead, store covered in the fridge. Reheat gently on low heat with a splash of milk, stirring constantly. Fold in pesto just before serving to keep it vibrant.
What if my pesto is very strong or salty?
Start with less pesto than the recipe suggests and add incrementally, tasting between additions. If pesto is already salted, reduce added sea salt. You can also thin pesto with a touch of olive oil before folding in.
Can I freeze pesto mashed potatoes?
Freeze unflavored mashed potatoes for up to 3 months. Thaw in fridge overnight and reheat with milk. Add fresh pesto after reheating, since frozen-thawed pesto may separate or darken.
