What is Bolognese?

It is an Italian Ragu or tomato sauce with meat, traditionally cooked on low-heat for many hours. This version BWLOW just puts the “many hours” in the crockpot instead of on the stovetop.

What is The Difference Between Traditional Bolognese Sauce and Spaghetti Sauce?

Both sauces are red meat based sauces. However, bolognese has milk, making it a creamier sauce, instead of simply a tomato based sauce.

Why Do You Put Milk In Bolognese Sauce?

It makes the sauce richer and silky smooth. I highly recommend using whole milk!

Variations for Homemade Pasta Bolognese

Turkey bolognese– Use ground turkey or even shredded or diced leftover turkey.

Chicken bolognese– Use ground chicken or shredded leftover or rotisserie chicken.

Add shrimp or crab– Make it a seafood sauce as a twist on a classic.

Add ground pork– For another layer of flavor and richness.

Add Italian sausage– You can use mild, sweet, or hot based on your preference.

Add meatballs– You can add pre-cooked frozen meatballs.

Add mushrooms– Add your favorite whether it be morels, portobello, shitake, button, or cremini.

Add other vegetables– Such as diced bell peppers, spinach, zucchini, peas, or artichoke hearts.

Add other herbs/seasonings– Such as smoked paprika, Cajun seasoning, chives, or fennel.

Add caramelized onions– Caramelize the onions first and then, add them to the sauce near the end of cooking.

Make it vegetarian– Simply leave out the meat and use vegetable broth instead.

Tips And Techniques For Spaghetti Bolognese Recipe

How to thicken sauce in slow cooker? Cook uncovered in the last 30 minutes or mix in a small amount of a cornstarch slurry. I prefer the first method because it prevents an odd “chalky” after-taste.

How to make sauce thinner? You can add more water or broth.

Do I need to drain the fat from the ground beef? This is not necessary if you are using lean meat with low fat content. If using something else, draining fat may be required to prevent sauce from becoming too greasy.

What to use instead of red wine? Simply replace the red wine with more broth.

Use nonstick pot for browning meat– Because this prevents sticking and burning.

Fresh tomatoes vs. Canned tomatoes – Canned tomatoes are often ripened to a more appropriate point than fresh tomatoes are before being picked. They are also fully cooked before going into the cans which makes them more convenient. The only downfall is that they can be more acidic. Fresh tomatoes are obviously fresher, not as acidic but they do take a bit more time to cook. So make sure to adjust accordingly.

Adjust amount of Italian seasoning- More or less can be used, based on your preference.

Sugar alternatives- Try honey, maple syrup or even molasses.

Use low sodium broth and bouillon cubes- Because it prevents this meal from becoming too salty.
