Lazy Oven Cooked Frozen Vegetables

Another easy way (according to Good Housekeeping Cookbook) to cook frozen vegetables is to bake them. When baking a casserole, meat loaf, etc., just bake a regular sized box of frozen vegetables (for 3-4 servings), in a covered casserole along with your meat, placing it in oven so it will be done at the same time as main dish. I am not saying this is the best way to fix vegetables, but that this is an easy way to free you up for something else. I know life can be very busy. If baking at 325 degrees increase cooking time about 10 minutes. If baking at 375 degrees decrease time about 10 minutes. I put frozen broccoli spears into ingredients but any frozen vegetable will work.

Ingredients Nutrition

  • 1 (8 ounce) frozen broccoli spears
  • 1 -2 tablespoon butter
  • 14 teaspoon salt


  1. Preheat oven to 350 degrees.
  2. Put frozen vegetable, butter, and salt into casserole.
  3. Cover.
  4. Baking time depends upon the vegetable.
  5. Broccoli spears and brussels sprouts should bake between 40 and 45 minutes.
  6. Broccoli chopped, whole kernel corn, spinach leaves or chopped, squash, and peas take 45 to 50 minutes.
  7. Cauliflower takes 50 to 55 minutes.
  8. Asparagus cuts and spears, any version of green beans, baby lima beans, mixed peas with carrots, and succotash take between 55 and 60 minutes.
  9. Mixed vegetables and wax beans cut take 60 minutes.

This actually works. (Yes, I was surprised)

I was making an extremely small meatloaf, and couldn't bear to waste all that nice convection oven heat, so I threw a small bag of butter-sauced frozen vegetables (minus the butter sauce pellets) into a small baking dish, baked for 10 minutes covered, then baked for 30 uncovered, then added back in the pellets and covered again for 10 minutes.

These aren't stunning roasted vegetables, but who expects them to be? But they are way nicer than microwaved.

Thank you so much for posting!

Great way to cook veggies. I used a mixture of frozen broccoli and cauliflower. I put everything in a pan, covered and cooked on the grill. I cooked them at 375 for about 30 minutes. Yummy side dish.
