Roast beef somehow tasted even better with a side serving of this vegetable casserole.
Grandma's Secret Trick
When the zucchini, onion and bell pepper seemed juicy and watery, Grandma found that adding them uncooked to the casserole could result in a watery casserole. To prevent this, she sometimes steamed these vegetables along with the broccoli and carrots before mixing them with the remaining ingredients.
Grandma was such a good cook that she could hear the difference in the cooking sounds as the onions began to caramelize.
Grandma offered us delicious ways to eat more vegetables. This dish was one of the best.
