Basic Baby Food Purees

Steps

1. Wash and peel the sweet potatoes. Cut into 1-inch cubes.
2. Steam over boiling water for 12-15 minutes until completely soft (a fork should slide through with no resistance).
3. Transfer steamed pieces to a blender or food processor.
4. Add 2 tablespoons of water, breast milk, or formula. Blend until smooth, adding more liquid 1 tablespoon at a time until desired consistency is reached.
5. For first-time eaters (around 6 months), blend to a very thin, smooth consistency. For older babies (8+ months), leave slightly chunky to encourage chewing.
6. Spoon the puree into ice cube trays (each cube is roughly 1 oz). Cover with plastic wrap or a silicone lid and freeze until solid.
7. Pop frozen cubes into labeled freezer bags. To serve, thaw 1-3 cubes in the refrigerator overnight or warm gently in a small pan.

Why It Works

Single-ingredient purees let you control exactly what your baby eats — no added sugars, no thickeners, no preservatives, no “natural flavors” (which often means processed additives). Steaming preserves more vitamins than boiling, and freezing in small portions means zero food waste. You can also introduce allergens and new flavors on your own schedule rather than being limited to what is on the store shelf.

The Cost Comparison

A single 4 oz jar of commercial baby food costs $1.00-2.00. Organic pouches run $1.50-3.00 each. Two medium sweet potatoes cost about $1.50-2.00 and yield 12-16 oz of puree (equivalent to 3-4 jars). That is $0.15-0.30 per serving compared to $1.00-2.00.

A baby eating 2-3 servings per day from 6-12 months goes through roughly 500-700 servings. Homemade: $75-200. Store-bought: $500-1,400. Savings: $300-1,200 over the first year of solids.

Best Foods to Start With

First purees (6 months):

• Sweet potato, butternut squash, peas, carrots, avocado, banana

Second stage (7-8 months):

• Apple, pear, zucchini, green beans, oatmeal (blended)

Third stage (9-12 months):

• Blueberries, mango, broccoli, chicken, lentils, scrambled egg yolk

Tips

• Buy produce in season and on sale, then batch-cook and freeze. Farmers market “seconds” (imperfect-looking produce) are often half price and puree identically.
• Silicone ice cube trays are easier to pop frozen cubes out of than rigid plastic ones.
• Label freezer bags with the food type and date. Use within 3 months.
• Combination purees (once individual ingredients have been introduced and tolerated) add variety: sweet potato + apple, pea + pear, banana + avocado.
• A basic immersion (stick) blender ($15-25) does the job as well as an expensive “baby food maker.” You do not need specialized equipment.
• Avoid buying the “baby food maker” appliances marketed to new parents — a pot, steamer basket, and blender you already own do the same thing.
