Rolled Turkey Breast with Spinach and Ricotta

Why this recipe works for muscle gain

No meat in this kitchen carries protein with less baggage. Turkey breast is 114 calories, 23.7 g of protein, 1.5 g of fat and 0.4 g of saturated fat per 100 g raw. Expressed the way it matters when you are eating to a calorie number, that is 20.8 g of protein per 100 calories — ahead of veal top round (19.9), skinless chicken breast (18.8), pork tenderloin (17.4) and trimmed top sirloin (17.0). The 6 oz raw portion each person gets here is 40 g of protein on its own, before the dairy in the filling adds 8 g and the vegetables another 5. The finished plate is 54 g of protein for 436 calories; the closest thing on the site is the sheet-pan chicken parmesan, which gets 56 g but spends 478 calories doing it.

Fifty-four grams is one full feeding, with room to spare. The useful unit is not the daily total but the single sitting: roughly 0.4 g of protein per kg of body weight per meal, across three to five meals, is where the evidence points (Schoenfeld & Aragon, 2018), with the daily point of diminishing returns near 1.6 g per kg and a plausible ceiling around 2.2 (Morton et al., 2018). One plate covers a feeding for an adult of essentially any size. The protein is also complete and leucine-rich — the comparison of animal and plant protein sources on muscle protein synthesis is laid out in van Vliet et al. (2015) — so nothing has to be eaten alongside it to make the amino acid profile work. The day's arithmetic, including how to spread it, is in our guide on how much protein you need to build muscle, and the rest of the muscle-gain recipes are portioned to the same logic.

The ricotta is a cooking device, and it is also most of the saturated fat. Part-skim ricotta is 138 calories and 7.9 g of fat per 100 g, of which 4.9 g is saturated. The 180 g in this recipe is 45 g a serving: 62 calories, 5.1 g of protein, 3.6 g of fat and 2.2 g of the plate's 5.2 g of saturated fat. It is in there because it melts rather than tightens, which is what keeps the inside of the roll wet while the outside takes 25 minutes of dry 425°F heat — a job that butter or a fat cap would otherwise do with twice the saturated fat and none of the protein. The Parmigiano brings 2.7 g of protein and 1.2 g more saturated fat for 7.5 g a serving, and it is also the only thing seasoning the filling. Whole-milk ricotta works and tastes better; it costs about 30 calories and 1.5 g of saturated fat a serving, which is a trade worth making on a Sunday and not on a Tuesday.

Two numbers to be honest about: the sodium and the carbohydrate. Sodium is 824 mg a plate, and the breakdown matters more than the total — 436 mg is the ¾ teaspoon of salt the whole recipe uses, 120 mg is the Parmigiano, 85 mg is the turkey itself, and the rest is the ricotta, the spinach and the cauliflower carrying their own. That is inside the Dietary Guidelines' 2,300 mg day for a dinner this size, and it holds only if you buy plain turkey: pre-brined breast, labeled as containing up to 8% of a solution, can carry 300 mg of sodium per 4 oz before you salt anything. The carbohydrate is the other honest number. At 16 g a plate this is a training dinner, not fuel for a long run — the version with potatoes instead of cauliflower in the variations below reaches 37 g, and if the point of the evening is glycogen rather than protein the carb-loading guide and the endurance recipes are built for it.

Tips from our kitchen

• Buy plain turkey, and read the fine print. A lot of boneless turkey breast in American supermarkets is labeled as containing up to 8% of a solution, which is water, salt and sometimes phosphates injected to stop people overcooking it — that can mean around 300 mg of sodium per 4 oz before you have touched the salt box, against the 20 mg in plain turkey. Pre-brined meat also will not take a sear properly, because it leaks. The label to look for says turkey breast, and nothing else.
• A thermometer, or don't bother. On a cut with 1.5 g of fat per 100 g there is no margin and no visual cue: the outside looks identical at 155°F and at 180°F, and the difference on the tongue is enormous. An instant-read thermometer costs less than the turkey. Push it into the thickest part through the end of the roll if you can, so you are reading meat and not the ricotta down the middle, which runs hotter.
• If the breast is too thick to butterfly cleanly, cut it in two. Some pieces sold as a half breast are a lump rather than a slab. Cut the piece into two thinner slabs through the thickest part, pound each one, and lay them side by side with a ½-inch overlap to make your rectangle — the overlap seals as it cooks and nobody will ever know. Two small rolls instead of one also work and cook in about 18 minutes; the timing above is for a single 2½-inch roll.
• The cauliflower needs the room more than the heat. A pound and a half of florets on a half-sheet pan around the roll is right at the limit; on anything smaller, roast the cauliflower on its own second pan. Crowding is the only thing that prevents browning, and unbrowned cauliflower in a dish like this just tastes wet. Cut sides down on the first side, and leave them alone until the halfway turn.
• Without wine: ½ cup of low-sodium chicken broth plus 2 teaspoons of white wine vinegar, reduced the same way, then the rest of the broth. The sauce is a little flatter — the wine is doing acid and aroma at once — but it is a better answer than skipping the deglaze, which leaves the best-tasting part of the dish glued to the skillet.

Variations

• With potatoes instead of cauliflower, for a training dinner: 525 calories, 54 g of protein and 37 g of carbohydrate. Swap the 1½ lb of cauliflower for 1½ lb (680 g) of potatoes in ¾-inch chunks, tossed with the same tablespoon of oil and salt; they need the full 32 minutes and a turn. Same protein, 21 g more carbohydrate, which is the difference between a dinner that sits next to training and one that fuels it — the logic is in the carb-loading guide.
• Wrapped in prosciutto, the way a Northern Italian butcher ties it: 474 calories, 58 g of protein, and 1,124 mg of sodium. Lay 2 oz (60 g) of prosciutto in overlapping slices over the outside of the tied roll before searing. It bastes the lean meat from the outside as well as the inside and adds 4 g of protein, but it also adds 300 mg of sodium a serving — the single biggest sodium decision available in this recipe. Worth it once; not the weekly version.
• The roll on its own, no vegetable: 363 calories, 51 g of protein, 7.4 g of carbohydrate. Skip the cauliflower and the second tablespoon of oil and roast the roll on a bare pan for the same 25 to 32 minutes. This is the version to make when it is going over pasta e ceci or next to bread, or when you want the leanest two slices on the site to take to work.
• With chicken breast, if turkey is not in the case: 447 calories, 52 g of protein. Two 12-oz boneless skinless chicken breasts, butterflied and pounded, make two smaller rolls that cook in about 20 minutes to the same 160°F. The numbers barely move — chicken breast is 120 calories and 22.5 g of protein per 100 g against turkey's 114 and 23.7 — and the dish is the same dish. Turkey is the better buy in November and the slightly leaner animal.
• A sliced-cold antipasto, which is what Italy does with the leftovers. Chill the roll whole, then slice it thin — ⅜ inch, not an inch — and lay the rounds on a platter with a spoonful of the cold sauce, a few capers and a little raw olive oil. Eight slices feed a table of six as a starter. The filling sets firm when it is cold, which is exactly when the pinwheel looks best, and it is the reason to make this on Saturday for a Sunday lunch rather than the other way round.

Storage & meal prep

Sliced and in a container, 4 days in the fridge, and this is one of the rare roasts that does not get worse. Keep the slices in their sauce if you have any left, or sprinkle them with a teaspoon of water before you cover them; store the cauliflower separately or it goes soft against the meat. Lean white meat punishes reheating more than fat meat does, so the best two answers are cold, straight from the fridge — thin slices on bread with a little mustard or olive oil, which is how half of this roll actually gets eaten in practice — or warmed gently in the sauce in a covered pan over low heat for 4 or 5 minutes, never in the microwave at full power, which drives the water out of the turkey and the whey out of the ricotta at the same time. The whole roll, cooked, freezes for 2 months: wrap it unsliced, thaw it overnight in the fridge and slice it cold, then warm the slices in sauce. Do not freeze it raw and filled — the USDA advises against freezing stuffed raw poultry, because the center thaws and cooks unevenly. For a week of lunches built on the same logic, the Mediterranean meal prep guide has the batch arithmetic.
