Slow Cooker Four Cheese Penne — Dump-and-Go Dinner

Five ingredients go into the crock and a full pot of creamy four cheese penne comes out. Dried penne cooks right in the sauce, so there is no boiling water, no draining and no separate cheese sauce to babysit. Layer, cover, and let the slow cooker do the work while the rest of the evening happens on its own.

Slow cooker pasta sounds almost too good to be true, yet this four cheese penne proves the method works beautifully when the liquid is rich enough. Dried penne goes straight into the insert, followed by diced gorgonzola and slices of tangy goat cheese, a crumbled vegetable bouillon cube, and two cups of heavy cream poured over the top.

Over two and a half gentle hours, the pasta absorbs the cream while the cheeses melt into it, and the two meet in the middle as a sauce that tastes far more involved than five ingredients deserve. The bouillon does quiet, important work, seasoning every layer as it dissolves, so the finished dish never tastes flat. It suits a busy weeknight exactly as well as a relaxed weekend, because the active work takes ten minutes and the machine handles everything after that.

Ingredients

Why this recipe works

The trick to cooking pasta in a slow cooker is that the starch does double duty. As the penne softens, it releases starch directly into the cream, and that starch is exactly what a cheese sauce needs to cling rather than slide.

In a stovetop mac and cheese, a flour roux provides that body; here, the pasta itself thickens the sauce as it cooks, which is why the recipe needs no flour, no butter and no whisking. The cream reduces slowly under the lid, concentrating around the pasta instead of boiling away, so the ratio of liquid to dry pasta has to be generous enough to finish with a glossy, coating sauce.

The two cheeses are chosen for how they behave under long, low heat rather than for contrast alone. Gorgonzola brings salt, tang and that unmistakable blue depth, and it melts into the cream almost completely. Goat cheese is softer and milder, and its slices melt into creamy pockets that round out the sharper blue.

The bouillon cube dissolves into the liquid early, seasoning from within instead of sitting on top, which matters when the pasta is the only thing absorbing flavor. Cooked low and covered, the sauce stays emulsified; the lid keeps the temperature gentle enough that the cream never splits.

Notes and substitutions

Choose a gorgonzola dolce rather than the firmer, more pungent piccante if the goal is a sauce that melts smoothly; dolce is creamier and folds into the cream without leaving grainy bits. A fresh goat cheese log slices cleanly and melts evenly, so avoid the very dry, aged styles. For the penne, a standard bronze-die or ridged dried pasta holds sauce best; whole wheat versions absorb more liquid and may need an extra splash of cream. The bouillon cube should be a plain vegetable one; seasoned cubes with herbs can make the sauce taste muddled.

Equipment is minimal: a six-quart oval slow cooker suits this quantity comfortably, leaving room for the sauce to bubble without boiling over. A glass measuring cup makes pouring the cream easy, and a small sharp knife helps dice the gorgonzola and slice the goat cheese log into rounds.

Every amount here is the standard quantity for this dish in a six-quart cooker; if the cooker runs hot, as some newer models do, start checking the pasta forty-five minutes early. Leftover sauce tightens in the fridge, so keep a little milk on hand when reheating.

• gorgonzola: Blue cheese works the same way; for a milder sauce, use crumbled fontina or shredded mozzarella and keep a smaller amount of gorgonzola for flavor.
• goat cheese: Cream cheese makes an equally creamy substitute with a tang that suits the gorgonzola; ricotta also works, though the sauce will be slightly looser.
• vegetable bouillon cube: Half a cup of vegetable broth from a carton can replace the cube, but reduce the cream by a quarter cup so the sauce still thickens properly.
• heavy cream: Half-and-half can be used in a pinch, but the sauce will be thinner; add an extra ounce of goat cheese near the end to bring back body.
