Ingredients and Substitutions
WHOLE CHICKEN: Use a 3–6 lb bird; adjust roasting time accordingly.
ONIONS: White preferred, but yellow onions are a fine substitute.
GARLIC: Two fresh cloves recommended; jarred garlic also works.
LEMON: Fresh lemons only—bottled juice doesn’t deliver the same flavor.
ROSEMARY: Fresh sprigs are essential; dried rosemary won’t do here.
OLIVE OIL: Swap with avocado or canola oil; avoid margarine.
CHICKEN BROTH: Low-sodium broth keeps the gravy from becoming too salty.

FAQs
Lemon is acidic and helps balance the stronger flavor of the dark meat in the thighs and legs and the fat from the chicken skin. It also adds an exquisite taste and aroma you don’t want to miss as the chicken roasts.

Oh my goodness!! This is the best ever! I’ve been looking for this recipe. I used to make this and lost the recipe. The gravy is amazing
I couldn’t agree more regarding the gravy. I think I will put a whole chicken on my grocery list this week so I can enjoy the gravy with mashed potatoes.
This recipe looks delish. I am always looking for new ways to make gravy–are the pureed roasted veggies just the onions and the garlic? Excited to try this dish. Thanks for sharing.
Correct. The onions and garlic are the only vegetables. Hadn’t thought about this recipe in awhile but looking at the picture again is making me want some tonight. It is so good!
I will have to try that “instant gravy”! This is the second roasted chicken I have seen tonight. Guess what’s for dinner Sunday night? 😀 Looks great!
I love your instant gravy, I’ll definitely give it a try.

I agree…. gravy has always been my dad’s “doings”. I think I use flour or something, right? 🙂 This DOES look foolproof and delicious too! I do know how to roast a chicken, but haven’t used this method yet! What’s for dessert?
Gravy has always been a mystery to me, but this sounds easy and delicious!
Looking and sounding good! Unlike Amanda’s husband, mine loves rosemary, especially on roasted potatoes.
Sounds fabulous! My hubby despises rosemary, so I have to use other herbs. The gravy sounds divine!
THANK YOU! It’s funny, I bake all the time, but there’s certain cooking things where I’m a total novice. I’ve only recently started eating poultry again, and I’ve never roasted a whole chicken to save my life. Just today I was thinking about it, and was thinking that I need to find some detailed instructions. This sounds awesome and I’m definitely going to give it a go.
