How can I make cheap, smooth homemade Alfredo sauce?

The real stuff is expensive because it's still actually cheese. If you're gonna use the canned stuff, you're probably better off just leaving it out entirely (or sprinkling it on top at the table as-desired...)

It doesn't take a lot of cheese either - it's pretty strong stuff. You can probably get away with just a few ounces...

Are you absolutely certain that the "grittiness" is caused by the cheese not melting, and not because the sauce is curdling? If you cook it too long or too fast, that is what will happen.

If you must use the Kraft stuff (personally, I think it has no flavour compared to real Reggiano), try melting the cheese on low heat in a very small amount of cream first, before you add it to the main sauce pan. If it's still gritty, either it's curdling or you need to use a better cheese.

Cheap grated cheese is LOADED with anti-caking agents that make it pour out of the container easily. I'm not sure what these additives are, but they don't melt, and they taste like eating a spoonful of dry flour. If you use that sort of stuff to cook, it will ruin your sauce.

My rule is that I only cook with cooking ingredients. Products in the store that are made to be eaten as they are packaged are not for cooking with. Using that Kraft grated cheese in the table dispenser package as parmesan to cook with is like using a snickers bar as the chocolate in a truffle recipe.

I should add that some grocery stores do sell quality pre-grated parmesan. It is often located with the real cheese, not with the condiments or pasta sauce. This stuff is perfectly acceptable, although usually not top-notch. The grocery store near me (Wegmans!) grates their parmesan at the store from the same blocks of parmesan that you can buy.

This is an old question, but for the sake of completeness: Parmesan, even the high-end stuff, really doesn't melt well. I've found that in any sauce containing it, it's got to be grated as finely as possible, or you get little globules of it that won't ever dissolve. That's tough to do with pre-grated Kraft cheese, but if you can find a good price on block parmesan, use the finest holes on your grater, or a Microplane. Then incorporate it slowly into the sauce.

OOOH! I finally get to share the alfredo sauce recipe I developed for low fatness and good flavor, adapted in part from bechamil sauce out of Joy of Cooking:

1/2 cup flour 1/2 cup X virgin olive oil

Preheat oven to 250 degrees F / 100 degrees C

Set your oven proof pan (use one that has a good cover) corning ware can be used for this, on a burner set to medium or less, depending on your stove, when the temp has stabilized add the oil, when the oil has come to temperature, add the flour, stirring well until the mixture is homogeneous. Make a white roux, cooking the flour in the oil without browning it, the roux is finished when the raw flour taste is gone (um let it cool before tasting...hot oil and all). Note don't ever use wooden cooking tools to make roux, the wood will char and bits will break off making the roux bitter.

Now add milk (I use skimmed milk) and bring the temperature of the mixture up until the roux and milk have consolidated and the consistency is what you want. Take pan off burner for a bit whilst you make the next step.

Take a large onion, peel it and cut it in half, then stick 20 - 30 whole cloves into the onion near the flat base of the onion and place the onion in the white sauce (after it has cooled a bit, don't want to burn the onion or spice in the hot oil). Mince up fine garlic to taste, I usually use a half of a medium head of garlic but suit yourself, and add a by leaf. Put your ovenproof pan, covered into the oven for 3/4 hour. After time, take the pan out, remove the onion, bay leaf and any bits of clove which have broken off.

Turn oven down to 100 C / 212 F.

Season the sauce with what ever you like, I use a bit of Tabasco, salt and white pepper. Next take very thin slices or finely grated cheeses (thin slices work best) in smallish quantities and of various types and add them in to white sauce, carefully; DO NOT OVERWORK THE CHEESE if you do, you will wind up with stringy glops of cheese which will need to be fished out before this last step can be restarted. The last one of these I made had 1 ounce /28 gm of aged cheddar, 2 oz /56 gm of manchega, a bit of parmasan, and a bit of smoked gouda.

Put your pan back into the oven, checking in 1/2 hour and every 10 minutes after that to see if the cheese is disintegrating and becoming as liquid as the white sauce. Once this has happened, stir in the cheese gently, pulling any stringy globs off your mixing device, adjust seasoning and serve with whatever you want, parsley or cilantro on top is pretty, so is paprika, saffron, etc.

Not a true alfredo sauce, but has all the characteristics except the enormous saturated fat load.

Oh yeah, it isn't very expensive to make either.

Enjoy

The longer the cheese has aged, the better cooking quality, that's why Italian restaurants, at least the decent ones only use Reggiano to cook with. Things like Grano or less expensive cheese should be used as garnish. You need to take the cooked pasta, add it to the cream over high, until it is almost reduced to what you want, pull it off the heat, add a knob of butter, and a handful of shredded reg. The cheese will tighten the sauce so don't over reduce cream.

Different types of cheeses have different melting characteristics. Processed cheeses like American cheese melt more quickly and easily than most natural cheeses because they have low meting points. Among the natural cheese, the driest ones - if finely grated - tend to melt better than their moist counterparts because their protein is less likely to separate from the emulsion and coagulate into tough, chewy strands that diminish the appearance and texture of the dish. This is why knowledgeable cooks prefer to use "cooking cheeses" like Parmigiano-Reggiano (authentic Parmesan) for preparations like sauces, where the cheese must become well integrated. The longer this cheese has been aged, the better its cooking qualities.

As stated above, it only takes a cup of cheese per half quart of heavy cream. That makes a lot of sauce. Gratting it yourself is the best way. Be sure to use the long grating side of your grater. One wants to have the bigger shreedds, it makes for creamer melting and better blending. You kinda have to plan a little a head. Once you grate the chesse, for best results let it stand for twenty minutes or so to allow it to come to room temperature before adding it to the heated cream and melted butter. Don't be in a hurry. Slowly let the cheese disolve on low heat into the cream mixture. And remove it before it is completely melted but keep stirring this allows the finishing blending to happen without over heatting the cheese which causes that grainy texture. Try this and you'll never go out to a resturant for alfredo again.

I make this sauce quite a bit, it never turns out the same twice, i don't measure stuff! The secret is butter and grated not shredded Parmesan. If your sauce is clumpy add flour it does sometime fix it. I made it this evening and it was clumpy, but it was only because i couldn't find decent grated parm...
