12 Pot Roast Sides That Add Something New
Gravy-Catching Sides
1. Creamy Mashed Potatoes
Serve mash when potatoes did not cook with the roast. Drain them well, mash hot, and keep the seasoning simple for gravy.
2. Buttered Egg Noodles
Toss noodles with butter, parsley, and black pepper. They suit thick gravy and replace both potatoes and bread.
3. Soft Polenta
Cook polenta until smooth and finish with modest Parmesan. Spoon roast and gravy over it immediately.
4. Crusty Sourdough
Warm thick slices for dipping. Bread is the best choice when carrots and potatoes are already in the pot.
Green and Fresh Sides
5. Lemon-Garlic Green Beans
Blanch beans and finish with garlic oil and lemon. Their snap contrasts with tender beef and vegetables.
6. Roasted Broccoli
Roast broccoli until the tips crisp and add lemon zest. Avoid cheese sauce beside rich gravy.
7. Balsamic Brussels Sprouts
Roast halved sprouts cut-side down and add balsamic vinegar. Their bitterness balances sweet carrots and onions.
8. Apple-Arugula Salad
Toss arugula, tart apple, walnuts, and cider vinaigrette. This is the cleanest side for a heavy Sunday plate.
9. Mustard Cabbage Slaw
Dress cabbage, carrot, and parsley with mustard and cider vinegar. It can be made ahead and suits leftover sandwiches too.
Classic Extras
10. Herb Dinner Rolls
Warm small rolls during the roast’s resting time. Skip them when mash or noodles already supply starch.
11. Glazed Carrots
Roast or sauté carrots with thyme and mustard. Serve them only when carrots are not already in the pot.
12. Sautéed Mushrooms
Brown mushrooms before adding shallot and thyme. They deepen a simple roast but may repeat mushrooms already used in gravy.
