To make this recipe, you'll need a whole garlic bulb, Yukon potatoes, and baby spinach from the produce department. "Baby spinach works best here because you'll have less stems to deal with," Hahn shares. Then pick up some vegetable broth, butter, and sour cream and look in your pantry for olive oil, salt, and pepper. "If you want to make this recipe dairy-free and vegan pick up dairy-free butter and sour cream at the store," Hahn shares.

Can I Make The Roasted Garlic Mashed Potatoes In An Instant Pot?

If you are best friends with your Instant Pot, you may be wondering if you can speed things up a bit and forgo the stove when preparing the potatoes. The answer is yes — you'll still want to use your oven for roasting the garlic, but the Instant Pot is fair game for the potatoes.

"The Instant Pot is very handy for all sorts of cooking and especially for steaming and cooking vegetables. For the potatoes in this recipe, you'll need the rack that comes with the Instant Pot or better yet, a mesh steamer basket that is one of the Instant Pot accessories that can be purchased as an add on," Hahn explains. You'll add 1 cup of water to the Instant Pot and then put the chopped potatoes into the steamer basket or stacked on top of the rack. Seal the lid, select high pressure, and set the time to 4 minutes. When the time is up, stand back and release the pressure. Then drain out the water in the Instant Pot and return the potatoes to the inner pot.

The rest of the recipe will remain the same and you can use the Instant Pot inner pot to do the mashing and final mixing in. Just one less thing on the stove to worry about.

What Pairs Well With These Roasted Garlic Spinach Mashed Potatoes?

Roasted garlic spinach mashed potatoes are a delicious and flavorful side dish, and they pair well with a variety of main courses and complementary side dishes. For a classic pairing, roast chicken, complements the creamy potatoes and garlic flavors. You can add a simple pan gravy for extra richness.

A perfectly cooked steak such as filet mignon can be a great match for the savory mashed potatoes. Baked or grilled salmon, especially when seasoned with herbs and lemon, can be a light and refreshing option alongside the creamy potatoes.

If you're looking for a vegetarian or vegan pairing, consider dishes like roasted portobello mushrooms, a hearty vegetable stew, or a tofu or tempeh-based main course. A fresh green salad with a light vinaigrette can provide a nice contrast to the creamy mashed potatoes. Roasted or grilled vegetables like carrots, zucchini, or bell peppers can add variety and texture to your meal.
