Steps
Tap an underlined word for a quick explanation.
the oven to 400°F. Bring a large pot of water with the salt.
Preheat. Preheating means turning the oven on before you start, so it’s fully hot when the food goes in. Food that starts in a cold oven cooks unevenly and doesn’t brown the same.
How you’ll know: The oven beeps or its light clicks off, usually 10 to 15 minutes after you turn it on.
Bring to a boil. It means heating a liquid on high until it’s fully boiling before you move on. A lid on the pot gets it there faster, which makes it a good moment to chop something.
How you’ll know: Big bubbles break all over the surface, and they keep coming when you lift the lid.
High heat
Cook the penne 2 minutes less than the package says, then it.
Drain. Draining means pouring off liquid, like tipping pasta into a colander or spooning extra fat out of the pan. Pour hot grease into a can or jar, not the sink, where it hardens and clogs the pipes.
How you’ll know: Only a few drips are left, and the food isn’t sitting in a puddle.
High heatTimer: 9 min
Dolly’s tip: It keeps cooking in the oven, so a little firm now means just right later.In the same pot, heat the oil over medium heat and cook the onion for about 5 minutes, now and then, until soft.
Stir. Stirring means moving food around with a spoon or spatula so it cooks evenly and doesn’t stick. Unless the recipe says constantly, every so often is plenty, and it gives food time to brown.
How you’ll know: When you drag the spoon across the bottom, nothing is sticking or scorching.
Medium heatTimer: 5 min
Add the garlic and for 30 seconds, .

How you’ll know: When you drag the spoon across the bottom, nothing is sticking or scorching.
Fragrant. Fragrant means cooking until you can clearly smell it, usually garlic or spices, often in about 30 seconds. That’s the moment the flavor is ready, just before it can burn.
How you’ll know: You can smell it from a step back, and garlic is pale gold, not brown.

in the crushed tomatoes, oregano and pepper and let it for 5 minutes.
Stir. Stirring means moving food around with a spoon or spatula so it cooks evenly and doesn’t stick. Unless the recipe says constantly, every so often is plenty, and it gives food time to brown.
How you’ll know: When you drag the spoon across the bottom, nothing is sticking or scorching.
Simmer. Simmering means keeping a liquid just below a boil, with small bubbles rising gently. It cooks food evenly and lets a sauce thicken without scorching on the bottom.
How you’ll know: Small, lazy bubbles break the surface every second or so, and nothing is churning.
Medium heatTimer: 5 min
Take the pot off the heat and in the penne, tuna, corn and 1 cup of the cheddar.

Tip it into a 9x13-inch baking dish and scatter the rest of the cheddar over the top.
for 15 to 20 minutes, until the cheese is and bubbling at the edges.
Bake. Baking means cooking in the oven with dry heat all around the food. It cooks evenly from every side, so you can mostly leave it alone.
How you’ll know: It’s golden on top and passes the recipe’s check, like a clean toothpick or the right temperature.
Melt. Melting means gently heating something solid, like butter or cheese, until it turns liquid. Low or medium heat keeps it from browning or burning.
How you’ll know: It’s smooth and liquid, and butter may foam a little but hasn’t turned brown.
Timer: 18 min
Dolly’s tip: To make it ahead, cool, cover and chill it for up to 2 days, then bake for about 30 minutes from cold.Food safety: Rotisserie chicken, deli meat, canned tuna and cooked shrimp are already cooked. Keep them cold until you use them, and heat them until steaming hot if the recipe warms them.
