The "Sunday Roast" Blistered Carrots and Celery Root
MEAL PREP
**Naturally Whole30 / Traditional British.** The British Sunday Roast is a sacred institution, a meal meant to anchor the week. Strip away the fussy parboiling and flour-dusting that modern recipes insist upon, and what you are left with is pure culinary alchemy: root vegetables, animal fat, and high heat. This recipe exists for that Tuesday night when you are deep into Day 12 of your reset, staring into the fridge, and realizing a cold baby carrot isn't going to cut it. You need savory, caramelized, rib-sticking comfort with minimal human effort. Celeriac might look like a dusty meteor that crash-landed in the produce aisle, but beneath that gnarly exterior is a creamy, sweet, earthy vegetable that transforms under the heat of the oven. Paired with thickly cut carrots and blasted in a generous pool of duck fat or ghee, the sugars naturally caramelize and the edges blister into crispy perfection. Make a massive batch. These roots earn their keep all week—tossed into tomorrow's lunch salad, refried alongside your morning eggs, or eaten straight off the sheet pan while you decide what to do next.
Before you start
Cut the top and base off the celeriac so it sits securely on your cutting board.
Take your chef's knife and slice down the sides, following the curve of the root, to sheer off the tough, knobby skin before cubing.
Give the carrots a vigorous scrub and chop them.
There is no need to peel them if you are pressed for time, but make sure the carrot pieces are roughly the same size as the celeriac so they cook at the same speed.
Ingredients
- celeriac1 1/2 lb
- large carrots1 lb
- duck fat, goose fat, or ghee3 tbsp
- kosher salt1 1/2 tsp
- coarsely ground black pepper1/2 tsp
- garlic cloves6 large
- fresh thyme sprigs4 small
Method
- 01
Preheat your oven to 425°F and grab your largest bare baking sheet.
Do not line it with parchment paper—direct contact with the hot metal is how we get those blistered, deeply caramelized edges.
- 02
Pile the celeriac, carrots, and unpeeled garlic cloves directly onto the metal pan.
Pour the melted duck fat or ghee over the top, then sprinkle generously with kosher salt and black pepper.
- 03
Toss everything directly on the pan with your hands until every single piece is glossy and coated.
Do not be shy here; the fat is doing the heavy lifting, conducting the heat to blister the vegetables while delivering a massive payload of savory flavor.
- 04
Spread the vegetables out into a strict single layer.
Do not crowd the pan; if they are touching shoulder-to-shoulder, they will steam instead of roast. Divide them between two sheet pans if necessary.
- 05
Toss the sprigs of thyme on top and slide into the oven to roast for 35 to 40 minutes.
Unless your oven has severe hot spots, leave them undisturbed. This is how you develop a deep, dark fond on the underside.
- 06
Pull them from the oven when the celeriac is fork-tender and creamy on the inside, and the carrots have dark, blistered edges.
Squeeze the sweet, roasted garlic paste out of the skins to eat alongside the vegetables, discard the tough thyme stems, and serve.
Notes
Sourcing the fat is critical to the dish's flavor and texture.
Traditional British roasting relies on animal fats with high smoke points like duck or goose fat. If you cannot find them, ghee is a flawless substitute that delivers a similarly rich, nutty profile capable of withstanding a 425°F oven.
Roast your garlic cloves inside their papery skins.
This protects the delicate flesh from turning bitter and burning in the high heat. Once roasted, they transform into a mellow, sweet paste that you can squeeze out directly onto your plate.
These roots pay a massive meal-prep dividend all week long.
They hold up beautifully in the fridge in an airtight container for up to 4 days. To reheat without them getting soggy, throw them in a hot skillet with a little extra ghee for 3 minutes until warmed through and re-crisped.
Always verify your labels for hidden sugars if pairing this with commercial meats.
If you decide to serve these magnificent roots alongside a quick sheet-pan sausage or some chopped bacon, secure Whole30-compliant, sugar-free meats (like Applegate or ButcherBox) to protect your reset.
