Potato and Chard Stalk Gratin Recipe (2024)

FAQs

Can you cook and eat the stems of Swiss chard? ›

Chard stems take a little longer to cook than the leaves, but the whole plant is edible and delicious. It's a little bit sweet in the stems (which have a slight celery-like flavor) and pleasantly bitter in the leaves. Some people prefer to remove the stems from the leaves and cook them separately.

A “gratin” is any dish that is topped with cheese or breadcrumbs mixed with butter, then heated in the oven or under the broiler until brown and crispy, according to The Food Lover's Companion. The term au gratin or gratinée just refers to anything prepared in that manner.

I don't recommend soaking the potatoes in water ahead of time for our potatoes au gratin (as some recipes call for). Soaking them will cause them to lose some of their starch, which helps to keep this dish creamy.

If you stored the sliced potatoes in water to prevent discoloring, but didn't drain them well and pat them dry before adding them to the baking dish, you may have added extra water to the dish. You could have also used the wrong kind of potato, as some waxy potatoes can release more water than starchier potatoes.

Blood clotting: If you are on blood thinners, you may want to avoid Swiss chard due to its high vitamin K content, which plays a role in blood clotting. Allergy: If you are sensitive to grass pollen, you should avoid eating Swiss chard because inhaling vapor from boiling the vegetable may trigger rhinoconjunctivitis.

Dark, leafy green vegetables are among the most nutrient-dense foods. The leaves and stalks of Swiss chard, in particular, provide an abundance of vitamins, minerals, and powerful plant compounds.

Vinegar causes the potatoes to form a thin crust that further helps in retaining their shape. Vinegar increases the acid pH levels of water which further helps the potato just like when you add a little salt to the water while boiling eggs.

Potatoes au gratin are slices of pre-cooked (usually boiled) potato cooked in cream and topped with cheese which makes the gratin. Gratin Dauphinoise, on the other hand, is a dish made of thinly-sliced (not pre-cooked) potatoes that cook in cream. Dauphinoise traditionally does not contain any cheese.

Derived from the French verb gratiner — to broil — gratin is a process that involves topping a dish with either cheese or buttery breadcrumbs and baking or broiling until crispy.

Once they have been peeled and cut, raw potatoes will turn brown quickly. This process, which is called oxidation, happens because potatoes are a naturally starchy vegetable. And when exposed to oxygen, starches turn gray, brown, or even black. An oxidized potato is completely safe to eat.

How deep should a gratin dish be? ›

The vessel best suited for most au gratin dishes is, simply enough, an au gratin pan. It can be round, oval or rectangular, and most commonly it is about an inch and a half deep.

Because potatoes take a while to cook through, this dish tends to bake for an hour or more. Keeping it covered with foil for 2/3 of the cooking time will ensure that they are well on their way to doneness before exposing the top to the heat element for browning.

Like many leafy greens, Swiss chard shrinks drastically when cooked, so 1 cup of cooked Swiss chard will contain much more nutrition than 1 cup of raw Swiss chard. The other thing to mention in comparing cooked to raw Swiss chard is the presence of oxalic acid.

You can eat these greens both raw or cooked. However, cooking chards improves not only the nutrient availability, but also the taste. Swiss chard is susceptible to foodborne pathogens, like other leafy greens, so be careful about washing this veggie thoroughly before preparing it.

The large, firm leaves are mild, sweet, earthy and just slightly bitter; on the whole, it's a bit milder than spinach. The stalks -- which can be white, yellow, red, purple, pink, striped and so on -- resemble flat celery with a sweet taste slightly reminiscent of beets.

The flavor of Swiss chard mellows once it's cooked. Adding onions and garlic will impart a sweet flavor, or pair with salty bacon, white beans or creamy cheese to offset the bitterness. I love adding a touch of spice and squeeze of fresh lemon juice for a bright pop of flavor.
