Cook Once, Transform Twice

Here’s why leftovers lose: they come back as the same dinner. Pot roast is wonderful on Sunday, a little tired on Monday, and by Thursday it’s the container everyone pretends not to see. So let’s do it the other way. You cook one big, easy main — a pork shoulder in the slow cooker — and before anyone eats a bite, you split it into two dinners that taste nothing alike. A noodle skillet this week. A pan of cheesy enchiladas whenever you want it, straight from the freezer. Nobody at the table will say “pork again?” Promise.

This builds on No. 01, A Freezer You Can Actually Shop From. The freezer half of this plan is the flat quart bag from there, filed upright with a two-part label. Haven’t set up your freezer yet? You can still do all of this. You’ll just need a sheet pan (a flat baking pan with a rim) and a spot to stand the bag up.

The HearthIQ ruleSplit it before you serve it.

A big main turns into tired leftovers when everyone eats and the rest goes back in the pot to be “dealt with later.” (We all know how later goes.) It turns into two new dinners when you split it the hour it’s cooked: one share for this week, one frozen flat for later, one small one for lunch. Keep the seasoning simple so it can go anywhere. The real flavor shows up on the night, from a noodle packet or a can of enchilada sauce.

1 · Cook onceOne pork shoulder, five cups.

Buy a 3-pound boneless pork shoulder roast. Some stores call it pork butt. Don’t let the name fool you; it’s the same cut, and it comes from the shoulder. It’s tough and inexpensive, and that’s the whole point. Hours of slow, moist heat melt the tough parts until the meat pulls apart with a fork. Cook it on a day you’re home. Tonight’s dinner can come from your Use first bin while the pork does all the work.

1. 1

   Step 1: Rub it the night before · 10 min

   Mix 2 teaspoons paprika (smoked or regular), 2 teaspoons garlic powder, 2 teaspoons dry mustard and 1 teaspoon salt. Rub it all over the roast. Put it in a covered container in the fridge for 2 hours or overnight. Keep it cold right up until it goes in the cooker. A raw pork roast keeps 3 to 5 days in the fridge, so you can buy it midweek.

2. 2

   Step 2: Into the cooker · 5 min

   Lightly grease the inside of the slow cooker. Add ¼ cup water and the roast. The meat must be fully thawed: never start a slow cooker with frozen meat. Put the lid on.

3. 3

   Step 3: Cook low and slow · 8 to 9 hours

   Cook on LOW for 8 to 9 hours, until the pork shreds easily when you pull it with a fork. If you can, turn it to HIGH for the first hour, then down to LOW. Leave the lid on: lift it only to check if it’s done. In a hurry? Cut the roast into 4 pieces, cook 1 hour on HIGH, then switch to LOW. It saves about an hour.

4. 4

   Step 4: Shred and skim · 15 min

   Move the pork to a big dish and shred it: pull it into strands with two forks, one holding, one pulling. Pick out the big pieces of fat. Pour the cooking liquid into a bowl and chill it in the fridge; the fat floats up and hardens on top. Lift it off (that’s skimming) and stir the juices back into the pork. That’s what keeps it juicy weeks from now.

5. 5

   Step 5: Into the fridge within 2 hours · 5 min

   Spread the pork in shallow containers so it cools fast, and get it into the fridge within 2 hours of turning the cooker off — within 1 hour on a hot day over 90°F. Then split it, below.

Wondering if it’s done, or just soft? Pork roast is safe to eat at 145°F with a 3-minute rest. The long hours aren’t for safety; they’re for tenderness. Hours of gentle, moist heat are what melt the tough parts, and that’s exactly what a slow cooker is good at.

2 · The splitThree portions, three labels, before dinner.

The roast gives you about 5 cups of pulled pork. Split it the same evening, while you’re already standing there with forks in hand. Each portion gets a job, and a label that says what the job is.

• N

  Noodle night · 2 cups · fridge — A lidded container at the front of the fridge, in the Use first spot — the place for food that needs eating soon. It’s dinner within the next 2 days.

• E

  Enchilada night · 2 cups · freezer — A quart freezer bag. Press out the air, lay it flat on a sheet pan to freeze, then stand it up in your freezer’s Proteins zone (Zone D from No. 01). Freeze it tonight, while it’s fresh, not on the day it would have gone bad.

• L

  Lunch · 1 cup · fridge — A small container. It becomes two rice bowls later in the week.

3 · Day by dayWhat happens when, and how long it keeps.

Count cook day as day 0. Cooked pork keeps 3 to 4 days in the fridge, so the fridge portions have to be eaten by day 4. The freezer bag has no rush at all.

1. 1

   Step 1: The night before — rub the roast · Day −1

   Spices on, covered, into the fridge.

2. 2

   Step 2: Cook day — cook, shred, split · Day 0

   Slow cooker in the morning. Shred, skim and split in the evening. Fridge portions in the fridge within 2 hours; the enchilada bag goes flat in the freezer tonight.

3. 3

   Step 3: Noodle night · Day 1 or 2

   The pork, broccoli and ramen skillet below. About 15 minutes. Uses: the 2-cup fridge container.

4. 4

   Step 4: Lunch for two · Day 2 or 3

   Rice bowls from the last cup, with rice you already have. Uses: the 1-cup container.

5. 5

   Step 5: Last call · Day 4

   Anything still in the fridge is eaten today or frozen tonight. Not tomorrow.

6. 6

   Step 6: Enchilada night · Any night, within 2 months

   Move the bag from the freezer to the fridge the night before. Thawed in the fridge, it keeps 3 to 4 more days, so there’s no rush once it’s out. Frozen food stays safe as long as your freezer holds 0°F; the 2-month date is about taste, because it slowly dries out. Uses: the freezer bag.

7. 7

   Step 7: The day after enchiladas · +1 to 4 days

   Leftover enchiladas keep 3 to 4 days in the fridge. Reheat a plate until it’s hot in the middle, 165°F.

4 · Dinner one · about 15 minutesNoodle night: pork, broccoli and ramen in one pan.

Nothing about this tastes like Sunday’s pork, which is exactly what we want. A 3-ounce packet of instant ramen does double duty: the noodles are the base, and the seasoning packet becomes the sauce. Serves 4, about 1¾ cups each, in about 15 minutes. You need 2 teaspoons oil, 1 cup chopped onion (about 1 medium), 1 carrot, chopped small, 2 cups frozen broccoli stir-fry vegetables, 2 cups pulled pork, one 3-ounce package of beef-flavored instant ramen and 1 cup water or broth.

1. 1

   Step 1: Soften the onion and carrot · 5 min

   Heat the oil in a large skillet. Add the onion and carrot and cook until soft.

2. 2

   Step 2: Thaw the broccoli · 2 min

   Thaw the frozen vegetables in the microwave and drain them.

3. 3

   Step 3: Warm the pork · 1 to 2 min

   Add the broccoli and the pork to the skillet. Stir and heat through.

4. 4

   Step 4: Make the sauce · 1 min

   Stir the ramen seasoning packet into the water or broth and pour it into the skillet.

5. 5

   Step 5: Add the noodles · 2 min

   Break the noodles into pieces. When the liquid simmers, add them and stir so they’re wet. Cover and cook until the noodles are done, about 2 minutes. The pork should be steaming hot — 165°F — before you serve.

5 · Dinner two · about 30 minutesEnchilada night: from the freezer bag, in one pan.

Weeks later, the same pork comes back in disguise: a bubbling 9 × 13 pan of enchiladas under melted cheese. Makes 8. Heat the oven to 350°F. You need 1 can (15 oz) pinto beans, drained and rinsed, 2 cups thawed pulled pork, 1 cup salsa, 1½ cups corn (fresh, frozen or canned), one 4-oz can chopped mild green chiles, ½ teaspoon garlic powder (or 2 cloves, chopped), 1½ cups shredded cheese, 8 whole-wheat flour tortillas (10-inch) or 12 corn tortillas (6-inch), and one 15-oz can enchilada sauce.

The all-bean version of this dish uses two cans of beans. Here the pork takes the place of one of them. Chicken or turkey works the same way.

1. 1

   Step 1: Get the pan ready · 2 min

   Lightly oil or spray a 9 × 13-inch baking dish.

2. 2

   Step 2: Mix the filling · 5 min

   Stir together the beans, pork, salsa, corn, chiles, garlic and half the cheese.

3. 3

   Step 3: Warm the tortillas · 5 min

   Warm each tortilla in a dry skillet so it rolls without cracking. Stack them on a plate.

4. 4

   Step 4: Fill and roll · 5 min

   Spoon about ½ cup of filling onto each tortilla, roll it up and lay it seam-side down (the loose edge underneath, so it stays rolled) in the dish.

5. 5

   Step 5: Sauce, cheese, bake · 15 to 20 min

   Pour the enchilada sauce over the top and scatter the rest of the cheese. Bake until hot all the way through, 15 to 20 minutes. Leftovers go in the fridge within 2 hours.

Top them with whatever is already open: avocado, sliced green onion, olives, lettuce, radishes or a spoonful of plain yogurt.

6 · The last cupLunch for two from what’s left.

One cup of pork and one cup of cooked rice make two lunch bowls in about 25 minutes, start to finish. If you made a pot of rice in No. 04, this is where the last of it goes. Heat 1 teaspoon oil in a skillet over medium-high heat. Add 1 cup chopped vegetables (bell pepper, onion, corn, tomato or zucchini) and a pinch of salt, and cook until just tender, 3 to 5 minutes. Stir in the rice, the pork and a pinch each of garlic powder, oregano and cumin, and heat until steaming. Split between two bowls and top with salsa, shredded cheese or sour cream.

7 · Make it yoursThe same plan, with other mains.

Both dinners take any 2 cups of cooked meat. A roast chicken or turkey breast works in the noodle skillet and the enchiladas just the same, and the clock is the same too: 3 to 4 days in the fridge for cooked meat. Pulled pork also goes into sandwiches, tacos, quesadillas or a salad, if you’d rather the third portion be dinner than lunch.

Cooking for two? Make the full roast anyway, and freeze two flat bags instead of one. That’s two enchilada nights banked for one day of cooking.
