Let’s Talk Cozy: Why I Can’t Stop Making These Roasted Autumn Vegetable Pot Pies

I’m not saying I look forward to cold weather just for the excuse to crank up the oven and basically live off pot pies, but… I’m also not not saying it. Honestly, these Roasted Autumn Vegetable Pot Pies have gotten me through more than one gloomy Saturday. There was this one time my friend Becky, who swears she “can’t cook to save her life,” ended up eating almost half a casserole dish of this and then texting me for the recipe (though I suspect it was mostly so she could ask me to make it again).

Funny story—last fall I tried sneaking in a beet because I thought I was clever, and my partner nearly staged a rebellion. You’ve been warned, friends.

Why You’ll Love This (Or At Least Eat an Admirable Amount)

I make this anytime I’ve gone a little overboard at the farmer’s market (there’s just something about knobbly root vegetables in a basket, am I right?). My family goes crazy for it because the pastry top gets perfectly flaky and, honestly, I sneak as many veggies as I can in there and no one complains. If you hate chopping, I hear you; just grab the pre-chopped mix, no judgment. Oh, and if you’re a fan of mushroomy things but not mushrooms themselves? Me too—half the time I just double the carrots instead. Live and let live!

Here’s What You’ll Need (Give or Take a Root Veg)

1 large carrot (or a couple small ones, we’re not the carrot police)
1 parsnip (my gran used to swear by them, but truthfully, I use whatever’s in the fridge—swede, rutabaga, whatever)
1 small sweet potato
1 onion, chopped (red, yellow, shallot—it all works, but if you use red your pot pie will look a bit wild)
2 cloves garlic, minced (sometimes I use those frozen cubes, but shh…)
1 cup cremini or button mushrooms, sliced (if mushrooms aren’t your bag, double up on squash)
1 cup butternut squash, cubed (or acorn, or whatever orange mystery squash you impulse bought)
Olive oil—a good glug, not fussy
Salt & pepper, to taste
1 teaspoon dried thyme (fresh is lovely, but dried means one less market trip, so hey)
1 teaspoon dried sage
2 tablespoons flour (plain, all-purpose, or even wholemeal if that’s all you’ve got)
1 1/2 cups veggie broth (I’ve used bouillon cubes in a pinch)
1/2 cup milk or non-dairy alternative (oat milk doesn’t split, so that’s my favorite)
1 store-bought sheet of puff pastry (or make your own if you’re feeling ambitions, but, life’s short)
1 egg, beaten (optional, for brushing)

How To Make Roasted Autumn Vegetable Pot Pies The Way I Do (Roughly)

Preheat your oven to 400F (200C), unless your oven runs hot, then maybe set it a bit lower. You know your oven’s quirks. Toss all your chopped veg—carrot, parsnip, sweet potato, squash, onion, and mushrooms—onto a big baking tray. Give them a good drizzle of olive oil, season generously (I get a bit heavy handed on the thyme), then roast for 25 to 30 minutes. Stir halfway through. If anything starts to look a bit too toasty, just pull that bit out early—no stress.
While that’s roasting, heat another glug of olive oil in a big pan (I use my trusty Dutch oven, but a big skillet or even a hefty saucepan will do). Sauté the garlic until it smells amazing, then tip in your roasted veg as they finish. Sprinkle over the flour and stir like mad so nothing catches. It’ll get a bit pasty—don’t panic, that’s normal.
Pour in your broth (slowly, or just dump it in—either way works) and milk, and simmer until you have a thick veggie gravy. Probably five minutes, but honestly, go by eye. If it looks like a real stew and not soup, you’re set.
Taste for seasoning. This is where I sneak a spoonful for “quality control.” Adjust if needed—I usually find a pinch more salt does the trick.
Spoon your mixture into oven-safe bowls or a big pie dish. Unroll your pastry and cut it to fit. If you’re like me, you’ll patchwork the top a bit. It’s “rustic,” right? Brush with beaten egg if you’re on Team Glossy Pie.
Bake for 20 minutes or until the pastry is all golden and puffed. Keep an eye out—last winter I got distracted by a dog video and nearly burned one (still ate it, mind).
Let it cool for a few minutes; steaming hot stew has betrayed many a hungry cook.

Things I’ve Learned (Often the Hard Way)

If you forget the egg wash, it’ll still taste fab—it just won’t get that shiny finish. I forget half the time honestly.
Don’t get fancy and use super watery veg (like tomatoes). The filling gets a bit soupy unless you crank up the flour.
I used to try using phyllo instead of puff pastry, but it kind of just goes to pot—don’t recommend!

Variations I’ve Actually Tried (One Didn’t Go Great)

Once I mixed in a handful of frozen peas for a bit of cheeky color. Worked brilliantly.
I tried adding diced apple once—thought it was pretty clever—but it turned oddly sweet. Won’t be repeating that experiment any time soon.
If you’re vegan, just skip the egg wash and use a plant milk. I make this vegan about half the time now.

Equipment: What You Need (And What You Can Improvise)

Oven-proof bowls or a large pie dish. If you don’t have either, a deep baking tin works—just call it a “vegetable slab pie.”
Baking tray for roasting veggies (I once used a pizza pan. You do what you must).
Pastry brush is nice, but in a pinch, dab the wash on with your (clean) fingers. Once I used a bit of kitchen paper—ripped, but did the job.
Chopping board and a semi-sharp knife. Honestly, anything that cuts closer than a butter knife is fine.

How I Store It (Except When We Don’t Have Leftovers)

Will keep in the fridge for a couple days in a sealed container. Freezes pretty well, too. But, I have to admit, it rarely makes it past 24 hours at my place. By the next day, it’s usually been pecked at until only crumbs and a guilty conscience remain.

If You’re Wondering How To Serve: Here’s What I Do

Some folks would say leave it to stand alone (which is solid advice), but I nearly always serve it with a big green salad and a dollop of good chutney. Or, for weekend lunches, we sometimes go full British and pile it with mash and gravy, which probably defeats the purpose of the pastry top but who’s counting?

Pro Tips From a Serial Pie-Maker (i.e., My Past Mistakes)

I once tried skipping the pastry rest (didn’t chill it after unrolling) and the top slid right off in the oven. Learn form me—give it five minutes in the fridge if it feels floppy at all.
If you use store-bought broth, taste for salt first! Some brands are saltier than a bag of crisps.
Don’t rush the veggie roast—the sweetness comes out best when you let them get some colour, so just let them do their thing. I always regret it when I’m impatient here.

FAQ—Questions I Actually Get (Some More Than Once)

Will this work with frozen veg?
Sure, but they can get soggy. I suggest roasting them straight from frozen at a high temp till they start to brown. Not quite the same, but works in a pinch.
Can I make this gluten free?
Absolutely! Just use GF flour and pastry. There are some good ones out there these days—try Bob’s Red Mill or whatever your local shop stocks.
Is it possible to prep ahead?
I often make the filling a day or two in advance; just add the pastry before baking. Actually, I think it tastes better the next day, but maybe that’s just me. Oh—and reheat it covered so the pastry doesn’t burn before the inside is hot.
What’s a good side?
Honestly, if you’ve got some creamy mash or a handful of arugula (rocket, if you’re reading from the UK)—either is brilliant. My mate Dave likes it with pickled onions, which is… a choice?
How do I stop the pastry sinking?
I wish I had a perfect answer; just try not to overload the filling and bake on a middle oven rack. Even if it sags a bit, it still tastes great!
