Horseradish Roast Beef
The story
No cooking. That is the pitch. Good roast beef from a deli counter, a horseradish cream you stir together in ninety seconds, pickled onion, and arugula on a District Biscuit. Fifteen minutes, four sandwiches, and the only heat involved is warming the biscuits.
The horseradish is the entire personality of the sandwich and it should be stronger than feels polite. Roast beef is mild and slightly sweet, sour cream and mayonnaise are both soft, and without real sharpness the whole thing goes flat. Prepared horseradish, drained hard so it does not water down the cream, plus a hit of Dijon and lemon. Underneath, the District Biscuit brings the butter and structure that deli rye cannot, and its crisp edges keep the sandwich from compressing into a flat cold thing in a lunch bag.
That is the culinary canvas doing the least and still winning. It is the fastest savory build in the Studio, it requires no stove, and it travels better than almost anything else here.

Ingredients
- 4 District Biscuits, warmed and split
- 1 lb rare roast beef, sliced thin at the deli counter
- 1/2 cup sour cream and 1/4 cup mayonnaise
- 4 tbsp prepared horseradish, drained hard
- 1 tsp Dijon mustard and juice of half a lemon
- 1 red onion, sliced paper thin
- 1/3 cup red wine vinegar and 1 tsp sugar for the pickle
- 3 cups baby arugula
- 4 slices sharp provolone or aged cheddar, optional
- Flaky salt and coarsely cracked black pepper
How to build it
-
1
Toss the paper-thin red onion with the red wine vinegar, sugar, and a pinch of salt, then set it aside to pickle for at least 15 minutes.
-
2
Press the prepared horseradish in a fine sieve to drain off as much liquid as you can, which is what keeps the cream from going runny.
-
3
Stir the drained horseradish into the sour cream and mayonnaise with the Dijon, lemon juice, salt, and plenty of black pepper.
-
4
Taste the cream and add more horseradish until it is sharper than seems reasonable, since the beef and biscuit will both soften it considerably.
-
5
Warm the District Biscuits in a 350F oven for 5 minutes and split them so the flaky layers are open.
-
6
Spread the horseradish cream generously on both cut faces of every biscuit.
-
7
Layer the sliced roast beef loosely rather than pressing it flat, since air between the slices is what keeps the sandwich from eating dense.
-
8
Add drained pickled onion, arugula, cheese if using, flaky salt, and cracked pepper, then cap and serve.
Pro tips & swaps
- Drain the horseradish hard. Undrained, it turns the cream into a thin liquid that runs out of the sandwich.
- Make the cream sharper than you think is right. Beef, dairy, and biscuit all soften it, and a timid horseradish cream is the whole failure mode here.
- Layer the beef loosely with folds and air pockets. Pressed flat, deli meat eats like a single dense slab.
- Ask the counter for rare roast beef sliced thin. Well done deli beef is gray and dry and no amount of cream fixes it.
- Swap in smoked turkey or good ham with the same cream, which works on both.

Frequently asked questions
Can I make the Horseradish Roast Beef Biscuit ahead of time?
The horseradish cream keeps a week and the pickled onion keeps two, so both should be made ahead. Assemble within a couple of hours of eating, since the cream will eventually soften the biscuit.
What's the best biscuit to use for a cold deli sandwich?
A flaky biscuit with crisp edges, like a District Biscuit, is ideal because cold sandwiches compress in a bag over a few hours. Deli rye goes dense and damp, while the District Biscuit's structure and butter keep it eating well.
Can I substitute the roast beef in this recipe?
Yes. Smoked turkey, good ham, or thin-sliced corned beef all work with the same horseradish cream. Pastrami is excellent and needs nothing else adjusted. **Is there a gluten-free or vegetarian version of the Horseradish Roast Beef Biscuit?** For vegetarian, thick slices of roasted portobello or good aged cheddar with the same cream and pickle work well. The District Biscuit is wheat-based, so check with the District Biscuit cafe about gluten-free options.
How sharp should the horseradish cream be?
Sharper than tastes right on its own. Straight from the bowl it should make you blink. Once it meets mild roast beef, a buttery biscuit, and dairy fat, it lands exactly where you want it.
What should I serve or drink with a Horseradish Roast Beef Biscuit?
Salt and vinegar chips, a dill pickle, or a simple green salad. For drinks, a cold lager, a dry cider, or iced tea.
How many calories are in a Horseradish Roast Beef Biscuit?
A single build lands roughly in the 460 to 570 calorie range, which makes it one of the lighter builds. Using all sour cream instead of the mayonnaise blend trims it further.
How do I store and reheat leftovers?
No reheating needed, since this is a cold build. Store the cream a week, the pickled onion two weeks, and the beef per the deli date. Assemble fresh each time on a warmed District Biscuit.
What makes a District Biscuit different from a regular biscuit?
District Biscuits are made with crisp, buttery edges and distinct flaky layers engineered to be a legit sandwich base, not just a side. In a cold build that sits in a bag, that structure resists the compression that flattens deli bread. It is your culinary canvas, built to carry big flavor from first bite to last.
