Method
Step-by-Step
- Place the evenly cut potatoes in a large saucepan and cover them with salted water. Bring the water to a boil, reduce the heat, and cook for 10 to 15 minutes, until the potatoes are fork-tender but still hold their shape.
- Add the frozen peas during the final 3 to 5 minutes of potato cooking, or cook the peas separately according to the package directions. Drain the potatoes and peas thoroughly so extra water does not thin the cream sauce.
- Melt the butter in the same saucepan over medium heat. Whisk in the flour and cook for about 1 minute, stirring constantly, until a smooth pale roux forms without allowing it to brown.
- Gradually whisk in the whole milk, adding it in a slow stream while stirring to prevent lumps. Cook for 4 to 6 minutes, stirring often, until the sauce thickens and begins to gently bubble.
- Season the sauce with the salt and black pepper. Taste carefully and adjust the seasoning only if needed, remembering that the potatoes were cooked in salted water.
- Fold the drained potatoes and peas into the hot cream sauce. Warm everything gently for 1 to 2 minutes, then serve while the sauce is smooth and the vegetables are hot.
Notes
Use small red or new potatoes because they hold their shape well. For a richer sauce, replace 1/2 cup of the milk with light cream or half-and-half. An optional 1/2 teaspoon of sugar may be added when using frozen peas. The sauce thickens as it stands, so avoid prolonged boiling after adding the vegetables.
